 INTRODUCTION

 24th March 1983
 
 MEMOTEXT is a word-processing program specially developed to run 
 on the Sinclair ZX-81. It is supplied in the form of a ROM 
 cartridge that fits neatly onto the back of the computer. It 
 supports both the Memotech RS232 and the Memotech Centronics 
 interfaces, and can therefore be used with a large number of printers.
 
 The main features of MEMOTEXT are as follows:
 
 - The Keyboard input routine is completely redefined. 
   Input can be done at full typing speed.
 
 - Two complementary sorts of file are supported. As well 
   as the normal text files, you can also set up data files 
   for mailshots etc.
 
 - You can set up prompts within, your text. Then, 
   whenever that file is printed you will be prompted for 
   certain information. You thus have the ability to set up
   general letters, and personalisemthem to suit specific needs.
 
 - Documents can be justified. The justification routine 
   uses a flip-flop algorithm to ensure an even ratio of 
   black to white all the way across the page
 
 - All normal word-processing facilities are available, 
   including Search/Exchange/Move functions.
 
 - The screen is "word-Wrapped" for ease of reading.
   (Words are never split over two lines).
 
 - Facilities exist to save each of your files
   individually, or alternatively you can save a whole 
   group together.
 
 - You can insert printer-specific commands within your 
   text so that if your printer has emphasising or 
   underlining capabilities etc., you can make good use of them.
 
 - Headings and page numbering are supported.
 
 - Certain information (e.g. Dates), can be set up when 
   you first enter the program. These will be picked up 
   automatically on printing, so you do not need to access 
   your text to put them in.
 
 The remainder of this manual will tell you how to take advantage 
 of all the facilities that MEMOTEXT has to offer.

 KEYBOARD LAYOUT
 
 The keyboard has been programmed to function as follows:
 
 Letter keys (unshifted)   Lower case letters
 
 Letter keys (shifted)     Upper case letters
 
 Space Key                 Space regardless of shift
 
 Full Stop/Comma key       Comma if shifted, otherwise
                           Full Stop
 
 Number keys (unshifted)   The relevant number
 
 Number keys (shifted)     "1" - Command symbol 
                           "2" - No effect 
                           "3" - Change to extended mode
                           "4" - No effect 
                           "5-8" - Move cursor 
                           "9" - No effect
                           "0" - Rub out character
 
 Symbol keys               To get the symbol on the key, 
                           you should press the Shift key 
                           and the Newline key together. 
                           this will result in the cursor 
                           shown on screen changing to 
                           solid black. You should then 
                           press the symbol key. Holding 
                           down the shift key at the same
                           time as pressing the symbol
                           will result in the symbol 
                           being shown on a black
                           backqround. Yrou should consult
                           the Memotech interface manual
                           to see, the ASCII character
                           that will be printed when such 
                           a symbol is met.
 
 The table above tells you how the keyboard is interpreted while 
 you are inputting test files. Under other circumstances there are
 monor differences. These differences are mainly restrictions.
 (MEMOTEXT incorporates the tried and trusted principle that it is 
 better to stop, you putting in wrong information at all, rather 
 than trying to sort out errors at a later stage.) 
 These differences are itemised below:
 
 1) While feeding in information on data records: 
      a) Shifted 1 and shifted 3 have no etfect. 
      b) Shifted 6 moves the cursor to the start of the next field. 
      c) Shifted 7 moves the cursor to the start of the previous field. 
      d) Pressing the Newline key on its own writes the record to the 
      file. (You should note that the unshifted Newline key has

 X MEMOTEXT x
 Page 3
 24th March 1983
 
    no effect during text file processing as line spacing on the 
    print-out is controled by commands embedded in the text file.)
 
 2) While feeding in information in response to selection prompts:
    Selection prompts are where you are asked to choose between 
    two or three possibilities. Here, you will notice that no 
    cursor appears at the bottom of the screen and that the first 
    letters of the various choices given in the prompt are 
    inverted. You should reply by pressing the appropriate 
    (unshifted) Ietter . No other reply will be accepted.
 
 3) While putting in information in response to "Function?" and 
    "Name?" prompts:
    The only valid characters are the unshifted Ietters and 
    numbers; the sideways cursor move keys (shifted 5 & 8); the 
    rubout key (shifted 0); and the Newline key to indicate that 
    you have finished entry .
 
 4) While putting in information in reply to other program prompts: 
    As 3) above except that you can use any symbol and also use spaces.
 
 5) While replyinq to "INPUT" prompts prior to printing:
    INPUT prompts are prompts that you have embedded in your text
    file and that will be used to prompt for information when you 
    come to print that text file.MEMOTEXT does not restrict the 
    length of your reply as it does with the other prompts, and 
    in fact you will be given the impression that you are setting 
    up a text file . However, you will not be able to put in the 
    command symbol (shifted 1), and the extended commands you can 
    use are restricted. You still have to use the extended 
    command "q" to end the input, just as in text files. (It is 
    too easy to hit the Newline key by mistake.)

 LIST OF COMMANDS
 
 The following commands are available within MEMOTEXT. Note that 
 they are all 3-letters, and that with the exception of DSP they 
 are simply the starting letters of the words describing the function.
 
 ADF - Amend Data File
 ATF - Amend Text File
 CDF - Create Data File
 CTF - Create Text File
 DDF - Delete Data File
 DSP - Display files currently in memory
 DTF - Delete Text File
 LAF - Load All Files
 LDF - Load Data File
 LTF - Load Text File
 MDF - Maintain Data File
 PTF - Print Text File
 RDF - Rename Data File
 RTF - Rename Text File
 SAF - Save all Files
 SDF - SAve Data Files
 STF - Save Text Files
 
 You should note that you cannot rename text or data files by the 
 ATF & ADF functions. You must use the Rename functions.
 Note also that function ADF only allows you to change what you 
 call the individual fields within a data file. To amend any of the 
 records themselves, (or indeed to create & delete records), you 
 need to use function MDF.
 
 More details on each of these functions follows in subsequent sections.

STARTING UP

When you first plug in MEMOTEXT and switch 
on the power to your computer, the first
prompt will ask you if you are using the 
Centronics or the RS232 Interface. In common 
with all prompts where you are asted to make 
a simple choice between alternatives, you 
should reply by typing the first letter of 
the alternative you require. If you are 
operating with a Centronics Interface you 
should reply "C", and with our RS232 
Interface you should reply "R".

When using the MEMOTECH RS232 Interface you s
should remember to set the Baud rate before 
you switch on the MEMOTEXT. (Refer to the 
MEMOTECH RS232 booklet for further
information)

Having specified the interface the prompt
"DATE1?" will appear. The information you put 
in in reply to this prompt will be 
substituted in your text files when you print 
them (assuming you have the relevant 
substitute command in your text files of 
course). As the prompt suggests, a suggested 
use for this is for dates, but if you want 
you can put in something else you might want 
to substitute, e.g. a reference of some sort. 
The next prompt is "DATE2?". Again this is a 
general substitute string and the previous 
comments apply.

You have now set up all the initialisation 
information,and have entered the main loop of 
the program. You will see the prompt 
"FUNCTION?". From now on you can execute 
various functions. As you finish each one you 
will be returned to this point in the program 
ready to start the next.

You can now therefore put in the 3 code-
letters of the function that you wish to use. 
If it is a valid function you will be 
prompted for further information specific to 
that function.

 LOOKING AFTER TEXT FILES - Functions CTF ; ATF ; RTF & DTF.
 
 1) PRINCIPLES OF TEXT FILES
 
 People use word-processors because they want the facility to be 
 able to modify documents easily. If you typed in the document in 
 exactly the format that you wanted it to be printed in, you would 
 have the same difficulties in modifying it that you would have on 
 a normal typewriter. For example, adding, or deleting a word may 
 involve not only adjusting the affected line, but also perhaps 
 many other lines to compensate for the addition/deletion.
 
 Sometimes you may be substituting different information in your 
 text every time you print it. Here you will have difficulty laying 
 out a format on the screen as the final appearance of the document 
 will vary conciderably depending on whether you have to substitute 
 one word or ten lines. As well as this of course, an A4 document
 normally has about 66 characters on each line, and there is no way 
 that this can be displayed on the 32-character screen ot the ZX81.
 
 The point to emphasise is that in using word-processors you should 
 not be trying to mkte what appears on the screen look like your 
 finished document. Rather, you should be using control codes to 
 tell the computer how to turn your text into the finished document. 
 Then, if you have to make a change to the document, you can normally
 just make the change in the text without having to worry about 
 knock-on effects. You have the further advantage that changing 
 indentation-etc. can normally be done simply by putting in a control
 code.	
 
 To illustrate this principle, imagine that you have just reached 
 the end of a paraqraph. On a typewriter,you would advance the paper 
 and start typing on the next line. On a word-processor like MEMOTEXT 
 you simply put in a control code to tell the computer to jump to the 
 next line at that point when it comes to print the document.

 2) CREATING TEXT FILES
 
 To create a text file you should reply CTF to the "Function?" 
 prompt. You will then be asked for a name. This is the name that 
 you want to give to the text file. It can be up to 9 characters 
 long. (If you put in more than 9, the excess will be ignored.) You 
 will find that you can only use letters and numbers and that you 
 must put something in.
 
 The next prompt you will see will be "Datafile Name?". A data file 
 consists of a number of records with "personalising" information 
 on them. A good example might be Name & Address records of all 
 clients on a mailing list. By associatinq the text with a data
 file you can use MEMOTEXT to produce the same basic document over
 and over again, substituting information from each record in the
 data file in turn.
 
 If you want to use this text with a data file you shculd put in 
 the name of the data file at this point. Otherwise just press Newline.
 
 You will now have set up an empty text file. At the top of the 
 screen you will see the name of the text file and of the data file, 
 and on the line below a cursor will have appeared. You can
 now start to put in your text and control commands.
 
 Note that unless yOU tell it differently the computer will assume 
 that you are printing a typical A4 document, and that there will
 be 66 characters on each line, 60 lines with printing on every
 page and 6 blank lines between pages. You can change all of these
 by suitable control commands.
 
 When you have finished putting in your text and want to get out of 
 the function, you have to use the extended control command "Q" 
 (for Quit) . Before allowing} you to quit however the program l,will
 check to make sure that there are no control syntax errors in your
 text. If it finds one, it will dispIay a meaningful enror message
 and show you where the error lies for you to correct. Otherwise it 
 will return you to the main loop and you will see the prompt
 "Function?"

 3) TEXT FILE PRINT CONTROL COMMANDS
 
 You can embed the following control commands within your text to 
 control how it is printed. The control command must be preceded by 
 the symbol " ", which tells the computer that the letters that 
 follow make up a control command. (This character is obtained by 
 pressing "1" while the shift key is being held down.)
 
 In the table below:-
 "nn" following a letter indicates that the letter must be 
 followed by a number up to 2 digits long.
 
 "nnn" following a letter indicates that the letter must be 
 followed by a number that can be up to 3 digits long (but 
 must be less than 150).
 
 "zz" following a letter indicates that the letter must be 
 followed by a number that is up to 2 digits Jong but which 
 may be zero.
 
 "bb" indicates that a number is not mandatory but that 
 numbers up to 2 digits long will be checked for.
 
 lf you use less numbers than the maximum you should ensure that 
 the text following the control command does not start with a number.
 
 Ann     Advance so that the next character 
         is printed in column nn of the line. 
         This command will be ignored if you 
         are already beyond this position in 
         the line or if nn is beyond the 
         width of the paper.
 
 Bzz     Leave zz lines between pages.
 
 C       Centre everything between this 
         command C ancl the next cammand C. If 
         you are not right at the start of a 
         line then an advance to the start of 
         the next line will automatically be 
         done in response to the first 
         command. However, no advance is made 
         after the second command C, so you
         can set up a title in the dead 
         centre of a line and still put a 
         page number on the right.
 
 H       Everything between two command H's 
         is considered to be a header that 
         will be printed at the top of every 
         subsequent page. Note that providing 
         there is no text before the first 
         command H in your text file then the

 * MEMOTEXT *
 Page 9
 24th march 1983
 
         header will be printed at the top of 
         page 1. Note also that you can put 
         in a new header anywhere in your 
         text file which will be printed 
         starting the next time a header is 
         produced, so that when you get to 
         the end of a chapter a new heading 
         can be set up.
 
 Izz     Indent zz columns. Thus if zz equals 
         4 subsequent lines will be printed 
         with 4 blanks on the left hand side. 
         To outdent you use the same command 
         followed by zeroes. Note that 
         characters will be printed using the 
         indentation currently in force, so 
         that if 10 characters have been 
         printed on a line and you then indent 
         30 columns the next character will be 
         printed in column 31. Conversely if no 
         characters have been printed on a line 
         and you indent to zero (outdent) then 
         no matter what the pretwious indendation 
         the next character will be printed in column 1.
 
 Lbb     Advance bb lines. Note that if you are 
         using justification then the line 
         immediately preceding this command is not 
         justified so that it loos like the end of a 
         paragraph. L on its own; L followed by 0; 
         and L followed by 1, all have the same 
         effect - they move the print position onto 
         the start of the next line. To leave 1 clear
         line between paragraphs you should use 
         command L followed by 2. For 2 clear
         lines use commancl L followed by 3 etc.
 
 Nnn     Stipulates that there are nn lines per
         page on which printing is possible. This 
         includes any lines used by the header.
 
 P       Move on to the start of the next page.
 
 R       Print everything between here and the end 
         of the line (which you would normally control 
         by using a command L)as	far to the right 
         of the line as possible.
 
 S1      Substitute whatever you keyed in in response
         to the "Date1?" prompt at

x MEMOTEXT X
Page 10
24th march 1983

        this point when printing.

S2               Substitute whatever you keyed in in reply 
                 to the "Date2?" prompt at this point when 
                 printing.


SD(Data-Field),  Go to the data file associated with this 
                 text file, and from the record currently 
                 being processed, take the data recorded 
                 for this Data-Field, and substitute it in 
                 the text at this point. Note that there 
                 must be a comma at the end of the command 
                 to tell the program which characters 
                 belong to the data field.

SP(Prompt),      Before printing display the prompt and ask 
                 for input. This input will then be taken 
                 and substituted at this point in the text. 
                 Again the comma at the end must be there 
                 to act as a delimiter.

                 To make it quite clear, in the previous
                 two commands you should put either the 
                 data field you want or the prompt you want 
                 between the first 2 letters of the command 
                 and the comma. Thus if you wanted to pick
                 up information from data field "ADDRESS", 
                 the command you would use is "SDADDRESS,". 
                 You can only use letters & numbers as part 
                 of these command strings.



U                Convert the hexadecimal numbers between this 
                 U command and the next U command to binary, 
                 and send them straight out to the interface 
                 at this point when printing. This is used 
                 to allow you to send specific control
                 commands to your printer. Basically you feed 
                 in a string of hexadecimal numbers (Your 
                 printer manual will often tell you what these
                 strings are), and MEMOTEXT will pass them 
                 through direct. It can be used to control 
                 underlining, character width etc. etc.

                 When you quit the text file FlEMOTEXT will 
                 check to make sure that everything between 
                 the two U commands is really hexadecimal. 
                 The error-message "Half-Number" indicates 
                 that there are an uneven number of digits, 
                 and so no

* MEMOTEXT *
Page 11
24th march 1983

                     conversion to hexadecimal is possible. 
                     If there are any spaces between the two 
                     command "U"s, the program will ignore them.

Wnnn                 Allow nnn characters to be printed on each 
                     line. (More correctly this might be expressed 
                     as setting the right hand margin position.)


Z                    Find the current page number and print it at 
                     this point.


- (minus sign)       In Memotext the command - 	is used to indicate
                     a soft-hyphen. (i.e. It indicates that the 
                     word can be split at this point if there is not 
                     enough room for all of it on the current print 
                     line, but that if it can all be fitted on the 
                     same line then there is no need to use the 
                     hyphen at all.)

4) EXTENDED CONTROL COMMANDS

- Whereas the normal print commands detailed in the previous secticn 
result in characters being inserted in the text file, extended 
control commands are used to perform complex functions within the
text itself.

The extended functions fall into 3 groups:-
     1) Fast scan through the files. 
     2) Quitting text file editing.
     3) Searching for/Exchanging/Moving blocks of text.

To get an extended command you should first prese the 3 key and 
the shift key at the same time. You will see that the cursor changes 
to look like " ". You must then press a code letter or number to 
perform the function you want. If you press shifted 3 by mistake, 
you can return to normal editing simply ty pressing shifted 3 again,
and the normal cursor will reappear once more.

4.1) Fast scan through the files

          Extended shifted 6  This causes an advance through the 
                              text equivalent to one entire screenful.

          Extended shifted 7  This causes the text to roll back
                              through	one screenful. 

     You should notice that the 6 & 7 keys. have arrows on them to 
     tell you which direction the text will move. If you have a very 
     long piece of text you may find it quicker to use the search 
     function described in 3) below to get to specific parts of the 
     text.

4.2) Quitting the text file

          Extended Q         When you have finished editing your
                             text file the only way to quit is to
                             use this comand. A simpler method 
                             would be too easy to hit by mistake.) 
                             Before allowing you to quit, the 
                             program will run through the text and
                             ensure that all the print control 
                             commands are complete and valid. If it 
                             detects an error, it will display that 
                             part of the text where the error ocurrs,
                             and tell you why there is an error at 
                             the top of the screen. Normally the 
                             cursor will be positioned in front of 
                             the command where the error lies. (The
                             exceptions to this are where you have 
                             used one command "C" or "H", and have 
                             not closed it off by a second.)

                                If an error is pointed out, you should 
                                correct it, and then try quitting again.
 
                                This "debugging" process will catch all 
                                logical errors in the print control 
                                commands, so that the only thing you 
                                will have to do when you print the 
                                text is to check the content and format.
 
 4.3) Finding/Exchanging/Moving blocks of text
 
           Extended F           This causes a search to be made through 
                                the file for a specific block of text.
                                You first must specify what you want to
                                find, so when you enter this command 
                                you will be asked for "Search String?",
                                You should type in the piece of text 
                                you want to search for. Spaces and the
                                print control symbol are	perfectly 
                                valid charactercs to be included in 
                                this search string. You must begin the
                                search string with a print control
                                character and end it with the same.
                                These two delimiting character will
                                not be used on the search, but. they
                                are needed to tell the program where
                                the string starts and ends. (As you
                                must have the facility to include
                                spaces in the string, there has to be
                                something to differnetiate between
                                where you want to have a space as the
                                last character in the search string,
                                and where is no space at the end.)
 
                                When you press Newline to indicate that
                                you have finished the string, the 
                                computer will scan through the file.
                                Whenever it finds a match it will 
                                display the prompt "Next"Stop?", and 
                                display the file at that point. If
                                this is the bit you were trying to
                                find you should press "S", ans you
                                will then be able to edit the file at
                                that point. Otherwise you should press
                                "N", and the program will search for
                                the next occurance of the string. If
                                it reaches the end of the file then it
                                will put you back into editing mode
                               at the begining of the file.

* MEMOTEXT *

HINT Because no lower case letters are displayed on the ZX81, you may
find that you sometimes put normal letters at the begining of sentences.
If you have a long text file you may find it useful to search through on 
strings such as "a"; b" etc. to check that you have not mised a capital.

This is used where you want to exchange one string for another.
You will first be asked for the "Search String?", and you should type in 
the string that you want to replace. The rules for its format are exactly 
the same as for the search string in the FIND function above. 
You will then be asked for the "Exchange String?", and you should type in 
whatever you want to go in place of the search string. The format is exactly 
the same as for the search string.

The program will then search through your text file stopping whenever it 
matches on the search string, and displaying the text at that point and the 
prompt "Ex./Next/Stop?". Replying "N" or "S" have exactly the same effect 
as in the FIND function. If you reply "E", then the matching text will be 
replaced by the exchange string and the program will proceed to look for any 
more matches. If the end of file is reached you will be put back into editing 
mode at the start of the text file.

HINT lf you are using the print control "U" character to put in printer-specific 
commands in your text, for such things as underlining etc., you may find it 
faster to put in a dummy string wherever you want such commands to go in the text, 
and then use this function to replace these dummies with the full hexadecimal 
control string.

This is used to move large blocks of text from one position in your file to another.

 * MEMOTEXT *
 Page 15
 24th March 1983
 
 It works like this:
 While still editing put two adjacent print control characters (shifted 1's)
 at the beginning of the block you want to move, and do the same at the 
 beginning of the block. 
 Position the cursor in the text file at the point where you want the block to 
 be moved and ONLY THEN use the extended M command.
 
 The program will then move the block; automatically remove the control 
 characters ; and then put you back in text file editing close to where the 
 block has been moved to. 
 It will not be able to do the move if you ask it to move the block 
 somewhere stupid - like in the middle of where it alreacly is, and you will 
 see the error message "Move in between" if you try. 
 Sometimes there may not be enough room to store the block that you want moved 
 while it makes space for it in the new position. So, if you see the message 
 "Short od space",you should try splitincg the block into ssub-blocks and 
 moving each of these in turn.

 5) AMENDING/RENAMING/DELETING TEXT FILES
 
 To amend a text file you should use function ATF, giving the name 
 of the text file in response to the subsequent "Name?" prompt. 
 This will take you directly into text editing mode at the start of the file.
 
 You cannot change the name of the data file associated with the text file 
 by this function. to do this you must use function RTF.
 
 To rename a text file or to supply a new or amended datafile name, you should 
 use function RTF. This will first ask you for the "Name?" of the file you want 
 to change, and then prompt you to supply its new name and any new data file name.
 
 Note that even if you are not changing a data file name (and the file needs one), 
 then you must reinput the old data file name, otherwise it will get lost.
 
 To delete a text file you should use function DTF. Immediately after you have 
 supplied its name, the file will be deleted. If you enter this function by mistake 
 you should type in garbage in response to the "Name?" prompt so that the program 
 will not be able to find a match.

LOOKING AFTER DATA FILES - FUNCTIONS CDF ; ADF ; MDF ; DDF & RDF

1) DATA FILE PRINCIPLES

Data files are files used to store sets of related information, that can be 
used to "personalise" letters etc. As an example, imagine that you have several 
customers and want to produce an invoice for them. You would use MEMOTEXT to set 
up a text file giving the format of the fnvoice, and then create a data file for 
your customers. The set of information or "record" would be all the information 
concerning one customer, and there would be 1 record for each customer in the data 
file. To produce an invoice all you would need to do would be to tell MEMOTEXT that 
you wanted to produce a print from the text file "INVOICE", and then scan through 
the data file "CUSTOMERS" until you found the customer record that you wanted to 
use to "personalise" that invoice. (You can also ask MEMOTEXT to produce an invoice 
for all customers if you so wish.)

Setting up data files is done by a 2-stage process. Firstly you define the name of 
the file and tell the program what sorts of information each record is to contain 
(i.e. the "Data-fields" in each record). Secondly you set up the records themselves.

Defining the data file is done by function CDF. You can change this definition by 
function ADF later if you want. To actually put information into the file, or indeed 
to change or delete information ,you use the MDF function.

To rename the file you use RDF, and to delete it you use function DDF.

Data files can be used by any number of test files. For example, a file of Names &
Addresses of customers could be used to produce invoices; statements; ant to send 
out price change notifications.

* MEMOTEXT *
Page 18
24th March 1983

2) DEFINING THE DATA FILE

Function CDF is used to define a new data file. You will first be asked to supply 
a name for the file. Having done this you will be asked to supply 6 field names. 
Each field name can be up to 9 characters long (normal letters & numbers only), 
and should be meaningful to you. For example in a customer file the first two 
fields may be "Name" and "Address1" representing the customer name and the first 
line of his address

These data field names are used for a variety of purposes. Firstly, when you come 
to use function MDF tc~ put the proper information into your data file, they will be 
used as part of the display to show you where each field is to go. Secondly, you will 
want to indicate which field is to go where in your text file , so that when you come 
to print, the correct information is picked up from the data file and substituted in 
the text. To do this you put the data field name in the substitute command in your
text file.

You should ensure that the most important piece of information coes in the first 
data field. This is because you may want to print a text file, and pick some 
information up from a data file, and be prompted by the computer to supply some 
other information. In order to tell you which data record is about to be printed 
the computer will display the contents of the first data file field on the record 
ue for printing as well as the prompt message. If you were producing statements and 
were supplying the statement amount you would probably want to know the name of the 
customer rather than a poctal code!

You can redefine the field names later- if you wish using function ADF. Note that 
neither of these functions will give you access to the data itself. This is obtained 
through function MDF.

* MEMOTEXT *

3) PUTTING INFORMATION INTO THE DATA FILE

Information is put into data files via function MDF - Maintain Data 
File. You will first be asked for the data file name, and then a 
screen showing the first data file record will be displayed. 
(Or if there are no records in the file the message 
"No More Records" will be there.)

The screen will display not only the contents of the record but also 
the data field names so that you know what every piece of information 
is. At the top of the screen you will see the prompt "Action?". 
The following are valid replies to this prompt.

A-     Amend the recorcd currently on the screen.

B-     Blank out the information currently on the screen and then 
       as action C

C-     Create a new record to be inserted after the one currently on 
       the screen. Normally you migtht choose to use action B for 
       most of your creations, but where a new record has a lot of 
       information in common with an existing record action C can 
       save you time.

D-     Delete the record currently being displayed. When the deletion 
       is finished the record prior to the one you have just deleted 
       will be displayed, or failinq that the 1st record in the file.

F-     Display the First record in the file.

N-     Display the Next record in the file.

P-     Display the Previous record in the file

Q-     Quit processing on the data file.

If you select actions A ; B or C. then the cursor will appear at the 
start of the first field on the screen. You can movee it between 
fields with the shifted 6 &hifted 7 keys. To indicate that you have 
finished dealing with the record you press NEWLINE, and the "Action?" 
prompt will reappear and you can make your next selection.

While using actions P or N to scan through the recordcs, if you reach 
the end of the file in either direction then you will see the message 
"No More Recs". This might also appear if you delee a record and none
are left in the file.

* MEMOTEXT *
Page 20
24th March 1983

MEMOTEXT will use "data compression" techniques on the records.
This means that if you only put 10 characters in a field, then
MEMOTEXT will only store 10 characters, so that you are able to
fit a large number of records in your file. Because of these 
techniques MEMOTEXT does not recognise spaces at the end of any field, 
so if you want a space at the end of any field when you come to print
a document, you must put the space in your text file.
You limited to 30 characters in any one field, but as nospaces are 
inserted at the end of fields, there is nothing to stop you making a 
larger field by putting the information into two adjacent fields and 
putting two substitute commands one after the other in your text file 
with no space in between.

PRINTING - FUNCTION PTF

To print your documents you should use function PTF. This will firstly 
take you through a series of prompts to establish the "rules" for how 
you want the print to proceed.

The first prompt you will see will be the "Name?" prompt. You should 
key in the name of the text file that you want to print. (You can not 
print data files direct - the data is picked up by substitute commands 
in the text.)

The program will then ask you whether you are using single sheets or 
continuous stationery by the prompt "Single/Cont?". You should reply 
S or C accordingly.

You will next see the prompt "Justify Y/N?". This is asking you whether
you want MEMOTEXT to insert spaces between the words in each line so 
that all lines end in the same column giving a neat block appearance. 
You should reply Y or N depending on whether you desire this option or 
not. In general terms, it will only be effective if your line width 
exceeds 35 characters. Certain printers have proportinal spacing 
abilities. If you are using such a printer MEMOTEXT will not be able to 
justify exactly, as it assumes that every character is the same width.

The next prompt asks for a "Page Number?". You must reply by keying in 
a number, even if you are not including page numbering in your 
document. The maximum number allowed is 159. You are allowed to put in 
0 to allow for a fronticpiece to your document. There is another reason
why page numbering does not automatically start at 1. This is to allow 
you to set up several "chapters" as separate text files, and to print 
them individually, but to allow consistent page numbering when you come
to put them together.

If there is a data file defined in the text file then the prompt 
"All/Select/Input?" will appear. The meanings of these are explained 
below.

All - denotes that you want the program to print one copy of the 
document for every record in the data file, (picking up "personalising"
information from each individual record in turn).

Select - denotes that you want the program to display each record in 
the data file in turn and ask you (by the prompt "Print/Skip?") whether 
you want to produce a copy using that particular set of information or 
whether you want to skip through to the next record without  printing.

* MEMOTEXT *
Page 22
24th March 1983

Input - denotes that you only want to procduce one copy of the document, 
and that you do not want to go to the data file at all, but rather have 
the program prompt you (using the data field names embedded in your 
text as prompts) to provide the information. This is a useful facility 
to test the format of a new document. It also may prove beneficial
when you want to produce something like an invoice for a casual 
customer who you never expect to do any further business with and who 
you do not want to set up as an entry in your data file.

If you reply A or S to the prompt and the data file is not currently 
present in memory then you will get an error message. In addition, if 
the program cannot find any field name specified in your text file, 
in the data file you will get a mismatch messacge.

If you have asked the program to prompt for information, either by 
replying I to the prompt above, or by substitute & prompt commands 
(SP(Prompt)) in your text file, you will then be prompted to supply the
requisite information. If a data file is being used at the same time, 
the contents of the first data field for the record currently being 
processed will be shown as well as the prompt so that you know which 
record you are dealing with.

You should note that input in reply to these prompts is put in to a 
screen that looks very much like that used for text editing. In fact in
some respects the screen behaves like the text editing screen. It will 
for example scroll up automatically if you fill it. However you will 
not be allowed to use print control characters, and the only extended 
command that you will be allowed to use is Q (which you must use to 
indicate that you have finished, because just as in text file editing, 
pressing NEWLINE by mistake would be too easy). You need not put any 
characters in if you do not want in reply to the INPUT prompts.

When the computer has all the information it needs to print the 
document, the printing will start. If you are using continuous 
stationery printing will start at once. If you have said that you are 
using single sheets the prompt "Press P to print" will be displayed, 
and printing will start when you press P. (For single sheets this 
prompt will also be displayed when the program, gets to the end of 
every page. You can if you wish reply Q to the prompt which will take 
you out of the PTF function.)

When the computer has finished the document it will either redisplay 
the 'Function?" prompt, ready for your next instruction, or, if a data 
file is being used, proceed to gather information for and print the 
text file using information from the next data file record, until all 
records in the data file have been processed.

To stop the print at any time you should hold down the shift key and 
the space key together. Thia may sometimes take a few seconds to have 
an effect.

SAVING & LOADING FILES
FUNCTIONS STF ; SDF ; SAF ; LTF ; LDF & LAF


MEMOTEXT does not use the same save & load routines as the normal ZX-81
, although the routines are similar enough to ensure that cassette-
recorders that load normal ZX-81 programs will load MEMOOTEXT files.

Within MEMOTEXT you have the ablility to load & save files individually.
This means that, for example, you could keep 1 data file, loading this 
separately, and then only load any text files containing standard 
correspondence as they were required.

If you are used to seeing the screen display while a ZX-81 program is 
loading or saving, you will notice some differences when you load or 
save a MEMOTEXT file. This is because these processes are carried out 
in 2 stages. There is first a burst of activity while the amount of 
space taken up by the file is transfered, (This is necessary to check 
that there will be enough space for the file in memory), then the 
screen goes silent for a while, and finally the file contents are 
transfered.

To save text files you use function STF, and to save data files you use
function SDF. The program will then ask you for the name of the file 
that you want to save. This is the name that the file will be saved 
under, and this is the name that you must use when you come to reload 
the file. Providing the file exists, the save will start as soon as 
you press the NEWLINE key, so you should start the cassette-recorder 
recording before pressing it.

To load text/data files you use functions LTF/LDF. Again the program 
will ask for the name of the file. It will then check to make sure 
that this file is not already present in memcory. If it is it will tell 
you, and stop the functicn. Otherwise it will scan the tape until it 
finds the file you want and then load it. If there is not enough space 
in memory to accommodate the new file, it will display a suitable error
message ansd stop the load. If this happens you should make some more 
space, probably by deleting from memory any files you are no longer 
using (remember to save them first if you have made any changes to 
them, and then try the load once again.

You also have the facility to save all files in memory, and then to 
reload them as one block. You might use this to save & load all your 
standard everyday letters at one go. The functions to do this are 
SAF & LAF. You must still supply a name when you save & load the files 
and you will not be allowed to use function LAF if there are any other 
files in memory at the time.

DISPLAYING FILES CURRENTLY IN MEMORY - FUNCTION DSP

To see what files you currently have in memory, you use function DSP. 
This will display the first file name at the top of the screen tell you 
whether it is a text or a data file. It will also ask if you want to see 
the next file. Pressing N will give you the next file, and pressing S will 
stop the function. When there are no more files left for you to see, the 
program will tell you that the end of files has been reached.

OUT OF SPACE & SHORT OF SPACE MESSAGES

If there is not enough space to load a file MEMOTEXT will give you the 
"Short of Space" message.

If during text editing or data file maintenance you run out of space, then 
you will get the "Out of Space" message and you will not be able to put in 
more information until you make more space. (By deleting records or deleting
some text or deleting whole files.)

During text editing the program is continually checking the space available. 
It will give you some warning if you are running outby displaying the 
"Short of Space" message. If you can finish the text in another few lines 
then do so. Otherwise you are advised to stop at the end of the sentence, 
and look for ways of making more room.

A PRACTICAL SCENARIO

Most of this document has been explaining how to put things into MEMOTEXT. 
In actual fact after a few days spent putting information and text in, you 
will only rarely need to do this.

Having set up your basic data files & text files a typical day might well 
be like this:

Arrive at work; switch on MEMOTEXT; load a file of normal letters; load a 
data file containing names & addresses of clients.
From time to time during the day go to MEMOTEXT; tell it which standard 
letter you want; if it is for an existing client scan through the data file 
for his details; if it is for a new client select the I option for data file 
printing and be prompted for the information needed by the standard letter.

At the end of the day switch off MEMOTEXT and go home.

Once a week add new clients to the name & address data files and make a new 
copy of this file for use from then on.

Once a month produce statements for each of your clients using the A option 
for data file printing.

Occasionally produce a new newsletter or product announcement or price list 
to be sent to all of your clients.


This manual was keyed in, formatted & printed using MEMOTEXT.
