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: DMKRIO and Herc
To my knowledge, there is no such thing as a 3350-1 and 3350-11 and you won't see any of these in DMKRIO. In the Hercules configuration file, you don't need to code the model (that is 11 or 1),

Hello Tom, You're correct. OCF used DDR for each drive so both used and free space was going to tape. Restores were equally messy and were at the mini-disk and not file level. My program was at the

Re: DMKRIO and Herc
3350 not 3330 model 11 an 1. I'll look at the file. How do you code the model number in the configuration file? Is that I'm the filee? Oct 23, 2022, 12:22 Ren¨¦ Ferland <ferland.rene@...> wrote:

Hi, It was a performance enhancement to place the header information in a different location. Actually, I wrote it as a VMFPLC2 parameter / option so it would work as IBM intended and as I needed. I
