DC_Icl - Invoke new CLI
RST 20H, DEFW $140C
IN:
BHL = null terminated CLI string C = length of string IX = input stream if BHL=0
OUT:
Fc = 0, successful Fc = 1, A = RC_ROOM ($07) if no memory or no free handle.
Registers affected after return:
..BCDEHL/IXIY same AF....../.... different
Notes:
This gives the CLI a string to execute. It is used by BASIC's *CLI command and by the Alarm popdown. Via this call all the CLI facilities can be accessed, though often it will be necessary to use the call to execute a file containing a list of CLI commands.
If IX=':INP' and BHL=0, the call fails without error.
Bugs:
Unreliable if HL points to string in segment 2.
