- Not to be confused with COMPACK.
COM-Pack is a DOS utility developed by Jack A. Orman. It combines multiple small COM files into a single "library" COM file. The user can then execute the library file, with a command-line argument to tell it which of the original files to execute.
Extraction and execution of the original file is apparently done all in memory. COM-Pack doesn't seem to provide a way to recover the original files from a library.
[edit] Identification
Library files are observed to start with bytes e9 46 01, followed by text that begins 0a 0d 20 20 43 4f 4d 2d 50 61 63 6b ("\n\r COM-Pack"...).
