This group is for all folks running the original IBM VM/370 Release 6 operating system (or later (e.g. VMTCE (Community Edition)) on Hercules. Like the other early IBM operating systems this version has always been in the public domain and so can be freely distributed. The base version as supplied by IBM is lacking in many facilities. IBM solved this by providing additional extension products which were licensed and so are not available. There are however many user enhancements available which can be installed. In addition, in order to get users up and running quickly updated "releases" of VM/370 included the most popular updates are available for download, so novices can start to learn VM without having to delve into the system internals. It is intended that this wiki will provide information on the base release and these updates.
The available versions are here :-

Re: VM/370 & SVC

Mark, If your work is on OS SVCs and you are familiar with OS please note that the OS emulation in CMS is based on OS/MVT release 21.8. I don¡¯t believe it was updated until VM/ESA (perhaps SP6) but

Mark, To the best of my recollection, all SVCs issued in CMS other than those in the 200s? (e.g., 202, 203), are used by OS simulation.? Thus SVC 8 is from an OS LOAD macro.? SVC 10 is

Re: VM/370 & SVC

GC20-1807 Looks right, for 202 & 203 but I think the SVC202 has been extended by mods. As SVC 8 is a OS/MFT call it won¡¯t be documented. Dave Sent: 05 February 2023 21:12 To: [email protected]
