VM was a rewrite of CP67. VM wasn't a "rewrite" of CP67, any more than z/OS is a "rewrite" of OS/360. It's a linear descendant; plenty of code remained. As a VMer for 40+ years, the truth has been in here, but: - CP-40 was started in very late 1964, on a modified 360/40 - CP-67 was indeed 1967, on a 360/67 - The VM/370 product was announced June 30, 1973 For all this and more, read Melinda Varian's definitive paper on VM history, 1964-1997, at http://www.leeandmelindavarian.com/Melinda/25paper.pdf I'm assuming from having never seen a reference to such on IBM-MAIN that no such community resource exists for z/OS-correct? ...phsiii ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ________________________________ This e-mail message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
