Ponder how few programmers have failed to lament the lack of QPAM. I suppose in the days of tiny memories, there were better uses for the bytes. That was then, not now. I'll grant that VSAM is the answer. Why has the right question not been asked? But VSE has embraced VSAM, relatively enthusiastically, I understand. Perhaps because the alternatives it offered were so dreadful. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
