A couple years ago, you were uncomfortable when you learned that IBM had (quite a while previously) repaired a similar obvious error concerning the ordering of SYSIN DD overrides.
The above (mis-)behavior would have been forgiving in some cases when the programmer misspelled IEFDRER; fixing it would have broken at least some existing JCL. But I support repairing such things, at least at release boundaries, and with sufficient notification. A validation tool also helps. -- gil ---------------------------------------------------------------------- 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
