Kees: I, too, found that a simple SuperC of even the DCollect output wasn't helpful because it requires comparison at the byte level. That loses which record the delta is from since SuperC only reports the byte offset from the beginning of the file. (or, at least, *I* don't know how to retain the record# with SuperC; I haven't pursued it.)
Do you have SAS available? If so, I have a crude SuperC-esque routine that I cobbled together for the very same reason which uses the DCollect output. It won't tell you the SMS fields that changed but, rather, columns with deltas plus new/old values. That, combined with the IdcAms manual appendix on DCollect record layouts, you can manually review where changes occur and investigate further. The SAS is 344 lines which expects sorted DCollect records from the two different SCDS's. I've built JCL in a buncha (10) pieces since I have 2 levels of staging beyond the active and can compare any 2 of three in a pass. I do no editing with simple job submission for the pair that I want. Again, it's crude but slightly better than visually comparing ISMF screens. (which I *have* done before when I knew there were only a few deltas) Send me a private e-mail & I'll cobble together an xMit file for you. ps. for some reason, I get small deltas in the 'un-used' fields between two seemingly identical SCDS's. A curiosity for sure but small noise otherwise. --------> signature = 6 lines follows <-------- Neil Duffee, Joe Sysprog, uOttawa, Ottawa, Ont, Canada telephone:1 613 562 5800 x4585 fax:1 613 562 5161 mailto:NDuffee of uOttawa.ca http:/ /aix1.uOttawa.ca/ ~nduffee "How *do* you plan for something like that?"

I have 2 SMS SCDS's and need to know the differences between them. Is there a way to compare them understandably? IDCAMS print produces a huge amount of unusable output, SUPERC claims there are no differences, which is incorrect. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
