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 Hercules Optimisation
Thanks Dave For memory paging - I was wondering if IBM had a paging memory device (clearly not - thanks). Therefore (1) I am going to go ahead with experimenting with a small DASD drive for paging.

Re: VM/370 Hercules Optimisation
Adrian, 1. Can we up the number of CPU cores emulated - I know the answer if yes but will VM/370 use it? Do we need to change CP settings, and how? I suggest we try and target 4 given the state of

Re: VM/370 Hercules Optimisation
Its already much faster than my P390.... VM/370 only support two as an AP or MP but that¡¯s it. An individual user can only ever use one. On real hardware the extra work in keeping things in sync

Hi Dave, If you leave out the last dot it would be a proper decimal number, as a Rexx person I see the advantages of that ;-) best regards, Ren¨¦.

Re: CP Query
Hi Dave, From a quick look around, it seems like "query cplevel" was added by CP mod HRC019DK and it's output modified by HRC100DK and HRC200DK. There is a QCPBLOK COPY added to DMKHRC MACLIB which

CP Query
Folks I don't suppose that any one can help me. I want to stop calling the Six-Pack builds "beta" and just number them say 1.3.1, 1.3.2, etc. Any way I can fix most things but I can't figure out how

Re: VM/ESA era manuals?
Dave, I thought PDF only started round about ESA V2, but earlier manuals were all Book Manager. I get the feeling some of the PDF versions seem to have gone from the Publications web site... Dave

Re: VM/ESA era manuals?
I have lots of VM/ESA manuals directly from IBM that are in PDF format. I can't say that the released them all in that format, but surely quite a few of them. -Dave -- Dave McGuire, AK4HZ New

Re: Fortran I/O
Given the conflict, one of them has to be removed I suppose and I would vote to remove GCCLIB. The GCC EXEC does not set the TXTLIB because, apparently, it is possible to use either GCCLIB or PDPCLIB

Re: Fortran I/O
So the sequence 'fortran', 'load' then 'start' is using dynamic linking then? And I take it Drew's various 'gen' execs are doing static linking? Presumably the gcclib is not just used by gcc itself
