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: memset help

Re: memset help
Folks, Not sure if its what I actually said, but in essence, there should be no problems re-building GCC, its just I havn¡¯t done it for some time. There are issues withy disk usage on the GCCCMS ID.

I've never seen a commercial spam filter that was worth a damn, honestly. But that goes for most commercial software. The big issue with spam is the combination of sleazy people and clueless people.
