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: Time zone?
If you are running CE 1.1.1 then you need to follow the instructions in ¡°MAINT MEMO B¡± otherwise, you will build a CP without the VM CE mods. Its pretty straight forward, should take about 10

Re: Time zone?
Jay, I can confirm that the CP file to change is DMKSYS ASSEMBLE. You will need to check which is the current file. I am in the process of changing my 3 pack, 4 packs, 5 packs and 6 packs to have the

Hi Jay, The CP source member is DMKSYS ASSEMBLE.? To change it requires a re-assembly of the module and a rebuild of the Nucleus.? The information can be found in the IBM Virtual Machine

Re: Time zone?
I don¡¯t think you can. I remember writing a CP mod for VM/ESA 2.2 ish that added per-VM time zones clock offsets but I don¡¯t have that mod available.

Time zone?
OK, so for this VM n00b, how do I set the timezone like I would with PARMTZ in MVS? I'm using the CE 1.1.1 to run the TK4- system. I know the hardware TOD clock runs in GMT, but I'd like other things

Re: More Help Files
Hi Mark, I agree that the LKED command can produce members in a LOADLIB. In VM/370, the use of such a library is as input to the GEN3705 CMS command. It is possible that some other special purpose

Re: OS Link Macro - Was More Help Files
Hi Dave, The OS simulation LOAD SVC calls DMSSLN to load either a MODULE file or a TEXT file. In VM/SP, CMS added a relocating loader and could then process a relocatable MODULE or a LOADLIB member.

Re: OS Link Macro - Was More Help Files
Bob, So how does OS LINK work in VM/370? Do you need to construct an auxiliary directory? It says its supported in the manuals? Or modules that load at other than the default address¡ Dave Sent: 06

Re: More Help Files
Hi Dave, I see that the VM/370 LKED and GEN3705 modules are made from DMSLKD, DMSGRN, and DMSNCP. DMSZAP can patch a LOADLIB file. The only 'loader' function in VM/370 is to read a 3705 control

It can't do too much harm. They were generally created on VM/370 where there is no spell check etc. No, I only looked at stuff on the "Y" disk. The next step will be to check what is on the "S". The
