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 :-

The bREXX bug with literals in the parse template does not break running editor macros in general. If anybody knows of a XEDIT macro where this bug would change behaviour, I'd like to see it. I am

BREXX in MVS 3.8j , and in VM/370 does not handle literals when you use PARSE ARG, or ARG. The problem was discussed in earlier e-mails: Rexx PARSE on VM/SP 5 behaves different from BRexx on VM/370 CE

Re: Do I have a looping issue?
If OSTAILOR was meant to help in OS development (which I agree it could come handy) it would be perfected by addition of EXT+ SVC+ PGM+ MCH+ commands to allow for tracing of all or selective codes.
