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: Two New Projects
Hi Jim, I think your problems with NOT ATTACHED and NOT ACCESSED are arising because you are logged on to GCCCMS. I'd suggest trying to build the code while logged on to CMSUSER. GCCCMS is only for

Re: GCC under VM370 CMS
Joe, Thats fine but in VM the console is not a 3270¡. ¡ if you use that code you will sometimes generate a wait. Look at the source of the CLRSCRN module. Dave Sent: 24 January 2021 12:27 To:

Re: GCC under VM370 CMS
The actual code you want is x'1140403C40400013'. In 3270 data stream, that means: x'11': Set Buffer Address x'4040': Row 1, Column 1 x'3c': Repeat to Address x'4040: Row 1, Column 1 x'00': Character

Re: GCC under VM370 CMS
There are lots of incarnations. It was late and I was rushing. What I should have said is that there is the source of a CLRSCRN module on the MAINT CMS mods disk but the module on the ¡°Y¡± disk but

Re: GCC under VM370 CMS
Hi, again, Tom, The first thing to understand is that in VM, with CMS, the "console" when it is a 3270 operates in two "modes" -- a line-at-a-time mode where it is emulating a keyboard printer (3215)

Re: Two New Projects
Hi, Tom, I recall we had MTS LISP running under VM/CMS back in the late 1970s. The way it was done, someone wrote a small "layer" or "jacket" or "wrapper" for all of the MTS system calls, and that

Re: GCC under VM370 CMS
Tom, You need to use a DIAG 58 call. There are no character sequences that clear the screen. I think the simplest solution is to create a ¡°clrscrn¡± module that loads in the transient area and run
