[MAINFRAME] 'The world economy runs on 15000 MVS Mainframes and some other stuff' Some people think they know IT and computing when they can operate a PC or a fax machine. This should make them think a bit. John _________________ 'Dave, There's a discontinuity in the CD-Roms. The LY manuals are licensed. They're not in some sets; in others but locked by a cryto key; and rumor has it, are unlocked in still other sets. I don't know which are with licensed manuals but my two sets are sans licensed material. FYI PeeCeeWeeNee's, the IBM manual sets, roughly 1,000 volumes for MVS are split into three general categories. The GC number sequence which are of general interest, JCL for example. The SC's for System Control... or something like that, and the really interesting ones the LY's which are licensed. The CD-Rom library includes several versions of MVS and the various subsystems and I'm told, I didn't count, that there are over 5,000 manuals on the CDs. One tragedy is that the CDs do not include really old manuals. Some of the discussions have been about 10-20 year old issues... because there are companies that are still running very old versions of MVS. What they don't realize is that the lynch-pin upon which MVS rides, VSAM Catalogs, stop working at midnight December 31, 1999. IBM has a replacement, ICF, which works well but ICF is not free and if a shop is running 15 year old MVS... well, they're in a world of hurt. It's ConvertCat time. So PeeCeeWeeNees, you will be laughing at bunches of big iron shops as Y2K comes, VSAM will stop. This is analogous to FAT breaking on a DOS or DOS/Windows system. Does anyone know where all the old licenses of MVS are and who's running them? Nope. There're out there though. Lots of them. Kinda like all the DOS-286's and DOS-Windows 386 machines. But back to the manuals.... Now, I don't see the point of locking the licensed material as you have to have a S/390 mainframe to even run the software... ...and there're not too many people who have those at home.
