The acronym REXX stands for Restructured Extended Executor Language and is part of the VM/CMS environment as the System Product Interpreter. This component is the EXEC (ie unixism :- script ) processor that is akin to PL/1 in grammar. Like most structured programs, it contains the constructs of IF,SELECT,DO WHILE, LEAVE, ... any the like. REXX also contains an interface to XEDIT (the visual editor).

REXX isn't just for VM/CMS anymore...REXX is the basis for the SAA procedures language, and IBM has committed to make it available in all SAA environments. It is presently available in VM, MVS/TSO, and OS/2 environments. I'm not an official anything, so nothing I say is accurate. Sam Drake / IBM Almaden Research Center
