PGMPAK is a program that compresses .EXE or .COM files, similar to
Microsoft's EXEPACK. Compressed files can be executed as regular .EXE files. The main difference between PGMPAK and EXEPACK is that
PGMPAK performs a REAL compression (normally 20 to 50%), while EXEPACK rarely gives you compression over 2%.
To run successfully PGMPAK you must have an IBM PC or true compatible running MS-DOS
2.0 or later and at least 256K bytes of free memory.
