In the early 1980s I was working as a GCOS systems programmer on Honeywell/GE mainframes, with little contact with IBM boxes. When I returned to the IBM fold (c. 1984) I found that SAM had been largely re-architected and was much as we see it today (except it was still 24-bit). The revised SAM was definitely bundled with DFP/XA, but did not become 31-bit code until MVS/XA SP 2.2. -- Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* david.w.n...@googlemail.com (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
