You're correct. You cannot change any migrated dataset, at rest. The ACS routines are only re-driven at recall. And, ALTER will probably recall. Then, you are stuck until the new retention period has expired. I'd suggest an HLIST output, parsed by a REXX programme to generate HDELs. I've not done it myself, but HLIST output is eminately PARSable. I did do it, with SAS, 20 years ago. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
