IRXJCL provides an "or ..." environment where the REXX interpreter can execute. And beyond IRXJCL, the programmatic invocation of REXX via IRXINIT allows the invoking environment to provide the storage management, I/O, etc. routines that the REXX interpreter will use so that REXX can be smoothly integrated into that invoking environment. I assume that is what SAS does. I *know* that is what NetView does. NetView initialization requires REXX; the primary initialization routines are written in REXX. The TSO REXX Reference manual goes into great detail describing how to run REXX on MVS in a non-TSO environment. And of course there are REXX interpreters that run in non-MVS environments with their own "or ...". (Take a look at Regina, for instance.) I've heard that even VM has REXX. :-) Pat O'Keefe ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
