Syntax: /E[XEPACK] or /E[EXEPACK]:1 or /E[XEPACK]:2.
EXEPACK causes pages of code and data in the file to be compressed. The OS/2 Application Loader will automatically decompress these pages when the program is run.
/EXEPACK:1 will use a compression algorithm that is compatible with OS/2 2.0, 2.1, and 2.11, as well as OS/2 3.0 and later.
/EXEPACK:2 will use a compression algorithm that is compatible with OS/2 3.0 and later.
/EXEPACK:2 will produce smaller executables that typically load faster.
