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: WAKEUP - does a emulation of this module exist
Sorry for the delay. As usual life gets in the way. SCHMAC MACLIB has been regenerated under VM/370 CE V1R1. ... Mark S

Actually, with latest hercules (Hercules version 4.4.1.10647-SDL-gd0ccfbc9). this is what I see in the file: 00000000? 9f 0d 0c 0a 0a 0a 0a 0a? 0a 0a 0a 0a 0a 0a 0a 0a? |................|

Re: A question about vm/370 print output

Great. thanks for detailed explanation. But that doesn't happen on z/VM or VM/ESA, and why do you see 4 more bytes after 0xff, but before form feed? It is not that you just see 0xff and form feed, but

Re: A question about vm/370 print output

Also, to be proper, such a "fix" should be even more complicated: it should not do its work when there are multiple non-space characters printed in the same position. Those would be meant as bold, or

Re: A question about vm/370 print output

Not true. Its possible to generate multiple "FF" characters in a print file. It appears to be when you tell CP to START a printer, so commence printing from the Spool. So a DRAIN and START, or a
