IEFSD095! In my early days (1968) working in POK, OS/360 System Design Department, I came across that very module -- and couldn't believe its blecherous code. It wasn't my assignment, but in not much time I rewrote it and ran speed tests, proving that my version was some multiple faster than the original. I couldn't get it integrated/shipped, of course, because of testing, regression testing, and other such fun reasons. Also of course, because OS wasn't spending that much time formatting large block letters on job output, so the overall improvement would have been minimal, at best. Ah, youth.

Anyone take into consideration the lack of skills nowdays. I am sure IBM is also running into this situation.
They're sort of coming full circle. The programming team on OS/360 had to start from scratch, and many had experience only on the 7094. The word orientation shows in IEFSD095 (big letter routine) that did character manipulation using word instructions, and almost no character instructions (IIRC, they used an STC, but that was about it). -- Gabriel Goldberg, Computers and Publishing, Inc. g...@gabegold.com 3401 Silver Maple Place, Falls Church, VA 22042 (703) 204-0433 LinkedIn: http://www.linkedin.com/in/gabegold Twitter: GabeG0 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
