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?
Also dave, If you look at the instruction, it is RS R1,R3,B2,D2 So, BA6610000 which is a compare and swap R6 and R1, moving R6 to R1 if they are equal... Here are the registers: 22:21:46.722 000060B8

Re: Do I have a looping issue?
Fish, I note your earlier remark "One should **NEVER** use OSTAILOR QUIET ". Like many Hercules users, I have downloaded and used many Turnkey clients like Volker's MVS TK3, Juergen's MVS TK4- and

Re: Do I have a looping issue?
Dave, Compare_and_swap is a non-privileged instruction. But he's getting a protection exception. Now how is that possible? If we look at his PSW ... 078D2000000383EC DAT is controlled by bit 5 in a EC

Well, I am the one in error this time :-(? But to my defense, I am not a Hercules person! :-) What would happen if OSTAILOR QUIET is coded? Would the error appear anyway? Just curious... Cheers, Rene
