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: Do I have a looping issue?
"In my opinion IEAVEVAL should be changed to prefer using TPROT as its first choice, and then only when that fails to accomplish its goal, to only THEN fall back to using its existing CS technique."

Re: #VMCE #rexx EE goes XEDIT - compiling a wish list

My POFILE XEDIT has for ages some filetype synonyms, like A for ASSEMBLE, E for EXEC etc. But, that initial setup was not perfect: if you happen to have a file named "TEST A A" you are unable to XEDIT

Re: Do I have a looping issue?
Ah - OK - it's the callable service IARBRVKR (which you could've mentioned). This claims to be a TPROT *replacement*, though it surely uses TPROT under the covers. Thing is, nobody is going to

Re: Do I have a looping issue?
That seems kind of muddled. IEAVEVAL *is* a service that does the check, using TPROT or CS as appropriate. Do you mean there is an *instruction* now that does the same check? If so, I'm not aware of

Hi Harold, Thank you for the very detailed explanation. I think is probably best to move this to the cRexx list seeing that there is work to do working to the solution. I¡¯ll invite you off-list and

The situation with 16M of memory and GCC compilations is a known consideration. I am not current with this topic although I was very much aware of what transpired due to the 16M constraint when it was

Re: Do I have a looping issue?
Hercules was never designed to operate that way. As the architectures expanded over the years, Hercules maintains the current level of the architecture. For S/370 that means Hercules emulates the LAST

This should be acceptable, XEDIT on z/VM 6.4 behaves this way. LCM+L's VM/SP 5 is down atm. This might be a typical task for the profile when EE will be able to run REXX-powered macros. Here an
