Introduction to GEM_calc This version 1.92 has been converted into English as a labour of love. The latest version I know of is 2.26, and can be obtained (in German) from Mr Englmayer. Use the program LOOK to browse through the GFA listing, or the instructions, which are quite detailed. I don't know the source of this program, but tip my hat to anon. The printer emulator comes from NEC (you may have noticed) and is necessary with 24-pin NEC printers to get good reports. If you need it, set it up in your AUTO file. GEM_CALC has been in the Top 10 PD lists in Germany for about 30 months. I hope you enjoy working with it as much as I do. B. Johnston Burenweg 36, CH 4127, Birsfelden, Switzerland
