The C version of PISTOL v2.0 was developed with BDS C compiler, version 1.45a and the L2 linker version 2.2 on an Exidy Sorcerer personal Computer with the S-100 expansion box. The Thinker Toys 2D dual 8" disk sub- system was used and total contiguous ram was 52K. Statistics from the BDS compiler indicated at least 14K left over at every stage. Thus it may be possible to recompile this in a 40K system. To run PISTOL.COM I believe the minimum RAM is 44K (this includes CP/M since the program code and all its buffers occupy about 33K). I/O requirements are minimal. A dumb terminal (video or printing) and the CP/M disk interface are sufficient. In use, the user may wish to customize PISTOL by declaring his actual screen width (I have defaulted to 64). Also the output scrolls and pauses after a fixed number of lines (my default is 20?). To continue, hit return, to abort type "q" before "return". Even the tab size for display is user alterable. See the documentation about the "system variables": TERMINAL-WIDTH , TERMINAL-LENGTH , and TAB-SIZE . To run type: A>pistol *** PISTOL 2.0 *** X>'core2 restore [note the initial apostrophe!] *** PISTOL 2.0 *** X> Documentation is largely available "on line". Try typing: X>help and try the menu selections. March 3, 1982 Ernest E. Bergmann Physics, Building #16 Lehigh University Bethlehem, Pa. 18015 (215-) 861-3932(at above)
