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: CP Query
Indeed, and I was just wondering how to report CMSLIB version, and of course GCC brexx etc all have versions. As for the distribution ... why not just have a version in a file on a shared drive and

Re: VM/370 Hercules Optimisation
Note the while VM/370 supports 16M of real memory, only the largest machines had that much installed.?? For example, the S/370 158 only supported 4M, and the uniprocessor 168 only supported 8M.??

Re: VM/370 Hercules Optimisation
I thought there was a bias towards 2305 devices for paging, but too much time hanging out with the documents for a certain 4361 and it's VM/SP flavor, my brain is probably fogged. -ahd-

Re: OK - So which version of Hercules ...
My opinion is that of the choices given, 3.13 is the only one that has sufficient stability for me to attempt to develop code for. I also find it to be the only game in town if building for any

Re: OK - So which version of Hercules ...
Adrian, I would compare the performance of 3.13 and 4.2.1. the released 3.13 code is getting a little long in the tooth. I think Roger may had added some fixes to the source (see the GitHub

Re: VM/370 Hercules Optimisation
Peter, I suspect that EPCS:VM produces a much bigger performance gain than AP or MP. ECPS:VM is the start of what eventually became SIE and microcode virtualization. So VM (aka CP) is a software

Re: VM/370 Hercules Optimisation
Adrian, In my experience, I doubt you are doing all that much paging.? First off, the VM/370 CP IND command doesn't show paging stats like it did in later releases, so it is difficult to know how
