        Programs generated with this version of program are not compatible
               with older versions because the local labels are identified
               by "M" as their control character, and the previous versions
               could not identify the "M" control characters. The ELI-IL
               release 2.xx and above also distinguish between local and 
               global labels when uploading or downloading program files.

                       DIRMEM

           called Calc/41.
           The Calc41.exe program supplied is same as the ELI-41SX program.
           The Calc41P.exe program is the POP-UP program.

           monitors.

           provided in the manual, except for the POP-UP. The Calc41P is loaded
           as a POP-UP by default. Another words there is no command line option
           to make it a POP-Up.
