REXX uses a few powerful, general-purpose programming functions and common arithmetical abilities, as well as OS/2 commands, within a simple framework. Existing batch files can be converted to REXX procedures, with more power and function. REXX is extensible with external DLLs programmed in a compiler language, whose functions are callable from REXX code.
REXX files only operate in OS/2 sessions, must have a file name
extension of .CMD
, and must start with a comment line
(/*....*/
), which distinguishes them from regular
command files.
REXX is not only available for &os2;, but as an add-on for other operating systems as well.
