I've written plenty of code that invokes language processors and other utilities in a batch environment, as have others, and I'd be very surprised if there weren't several such programs on the CBT tape. For that matter, most of you have probably used one such program from IBM, a real gim.

And I don't see how something like DDNAME= would help that in a TSO environment. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
