These are free programs for DOS and Windows written by Eric Tauck. For more information, visit the supporting web site at http://www.shoelesscomputers.com/software The directory "source" contains the source code for many of these programs. The programs are written in either assembly language or C/C++. The assembly language programs are written for the WASM assembler, which is available here. The windows programs require the Win32 class library "epp", which is also available here. Most of the C/C++ were written using Symantec C++ and might use features specific to that compiler.
