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 :-

What makes XEDIT *modern* ? VM/SP 3, when REXX and EXTRACT were added ? When (if?) VM/SP 5 at LCM+L ( tty.livingcomputers.org:24 ) is up: which *modern* features are missing ?

Fully agreed. I need to acquire more knowledge to enter this area. In the 1990s I was a very experienced professional assembler programmer on the Motorola M680x0 family. Used on bare metal including

Hi Ren¨¦, What I want to see in a full screen editor for VMCE, is the ability to use REXX as a MACRO language for the editor so we can implement new editor commands in REXX and issue 'address XEDIT'

I think it goes without saying that we would very much like to see Rexx compatibility for EE and a more XEDIT-like working - although it is not at all bad at the moment, just a bit different. Because

Re: Do I have a looping issue?
Real hardware has no mechanism to report to an operator any interruption. REAL hardware only reports interruptions to the running program, an OS in this case. So, no, real hardware will not report

Of course its desirable to have as much of XEDIT as possible under VM/370 CE, except of course it limits the memory available. I tend to use EE to work on CE. It would also be nice to see betas etc.

Hello, I would love to see XEDIT on VM/CE. I know you have a lot invested in EE, but have you thought about looking at the product KEDIT? While written for Windows 32 bit and most likely in C or C++,

No feedback ... are editors much less significant in the (emulated) mainframe community now since most people are doing it the Zowe way ?
