The cmd file extension is associated with the REXX programming language (REstructured eXtended eXecutor language) a language designed for the computer administrator.

It is an interpreted language, meaning each step of the program is evaluated and then executed each time the program runs.

REXX was developed and used internally at IBM for a few years before being made a part of the Virtual Machine/System Product (VM/SP) in 1983.

The cmd file stores batch file for OS/2 written in REXX programming language.

This cmd file type entry was marked as obsolete and no longer supported file format.
