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 :-

And the Internet turned fifty last week
Hello!
Read this and react: " Depending on how you look at it, the Internet turned 50 years old last week ( ) . On October 29, 1969, the first message was transmitted between two of the four nodes that made up ARPANET, the Internet's predecessor network. ARPANET was created after a million dollars earmarked for ballistic missile defense was diverted from the Advanced Research Projects Agency budget to research packet-switched networks. It's said that ARPANET was designed to survive a nuclear war; there's plenty of debate about whether that was a specific design goal, but if it was, it certainly didn't look promising out of the gate, since the system crashed after only two characters of the first message were sent. So happy birthday, Internet, and congratulations: you're now old enough to start getting junk mail from the AARP ( ) ." ----- Gregg C Levine gregg.drwho8@...

Re: Differences between S/380 and XA mode?
¿ªÔÆÌåÓýTimothy, ? I am not sure when XEDIT appeared, SP1 I think or REXX . Whilst folks have written a screen mode editor and installed a portable REXX on VM//370 they don¡¯t interact in the same way that XEDIT and REXX do on VM/SP which means many things don¡¯t work. ? Also note XA mode isn¡¯t virtualizable in the same way that 370 mode is.? VM/370 relies on the fact that the Store PSW is a privileged instructions so that a user mode program can¡¯t tell it¡¯s a use mode program. Some of the instructions introduced in XA mode expose the machines state back to a user mode program. This means you can¡¯t use the same trick. XA mode also introduced a new instruction called ¡°SIE¡± which stands for ¡°Start Interpretive Execution¡±. This means tweaking VM for XA mode isn¡¯t easy¡. Much simpler to run LINUX barefoot.. ?

Re: Differences between S/380 and XA mode?
¿ªÔÆÌåÓýTim, ? VM/380 mode simply allows access to more than 16Mbytes of memory. The memory above the ¡°line¡± is real, non-paged memory, so must be shared among all VMs that use it. It does not implement XA or ESA mode IO so you can¡¯t IPL a LINUIX system. That would really need a major re-write of CP the VM hypervisor. I can¡¯t see it happening. You can IPL LINUX directly under Hercules though, The POSIIX shell is licenced code so I can¡¯t see how it could run without a licence. There isn¡¯t even XEDIT in VM/370R6 (the release go R1->R6, SP1-SP6, XA SF, XA SP, ESA) so R6 is something like 10 release behind VM/370R6 ? Dave G4UGM ?

Re: Listserv, Relay, Xyzzy and TCP/IP.
I had not heard any replies yet that I recently asked for.From the original author of the Pascal version of Relay:Between VT moving away from VM/XA as part of Y2K and the demise ofSomeone is working on RSCS and IUCV for VM/370 R6. I have good Good news! Standard pascal compiler supports Pascal/VS as compatible so that Relay V2 pascal files can be compiled into module files. Who is author of Relay V2 so that I need to contact? I have Xyzzy chat programs but no original source elsewhere. I lost them (includes source codes) to drive failure. I need to contact author to get another copy. I can't find him through Internet so far. Thanks, Tim |
