I was working as a PL/1 and Assembler application programmer in 1975 when the switch was made from OS/VS2 Release 1 to MVS 3.7. I remember a few problems at the time, but also the increase in facilities then and over the next few years. Not always a smooth path thereafter, but like you say what we have now is vastly more capable.

My colleagues point out an interesting anniversary. IBM introduced OS/VS2 Release 2 (IBM Program Number 5752-VS2) on July 3, 1974. The history is a little complicated, but essentially it's the date when "MVS" was born. Today's z/OS 3.1 operating system is the direct, lineal descendent of OS/VS2 Release 2. Of course z/OS is vastly more capable and broader in scope. Happy 50th anniversary! OS/VS2 Release 2 was WAY before my time. Do you have any personal memories? ----- Timothy Sipples Senior Architect Digital Assets, Industry Solutions, and Cybersecurity IBM Z/LinuxONE, Asia-Pacific [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
