The MDRAW.DO files is the Mini-Draw Drawing. HNY.DO is a sample file to see some of the features of the program. There is a slight chance you may have to free up some memory by deleting any extra files on your machine to be able to load this! MDHELP.DO is a short HELP File. If you are like me you probably set up Wordpad to automatically read .DO files. If not load it into the Model 100/102/etc. and read and/or print it. Thanks for trying this program out. I had a lot of fun designing and coding it. It brought back a lot of OLD early computer memories (Sinclair, TI-99/4, Sanyo MBC500, Atari 1040 ST, PC-Clones, and other) of programming in BASIC, Pascal, and C. Please, Let me know if I need to fix anything. I am new to the group. David Grissom live from beautiful Prattville, Alabama December 31, 2003
