Hello Joe, Yes; but by CP (DMK) not aCMS program. I say this because diag 8 from a virtual system is for issuing CP command. Inside DMK/CP a diag 8 would go to Hercules. Bert

Joe & Bob DIAG is a privileged instruction. CMS machines always run in problem state, so when they try and execute a Diagnose instruction they don’t… Dave Sent: 19 November 2022 17:45 To:

Bob, Yes, it was my understanding a virtual machine can't talk to Hercules directly. What might be possible would be to add a new Diagnose instruction (say X'FFC' so as to not interfere with z/VM.

Gentles, That is why we have Hercules cp mod 10, the HCP command which allows a user ask CP to issue a DIAG 8 on the hardware it thinks it is running on. For many on here this will be Hercules, but if

"This parameter specifies whether a command issued through Diagnose 8 will be executed by Hercules as a Hercules commands or not." Joe

Dave, No, I'm talking about something like the STK4400. I was the lead programmer at Cray and also the VM programmer for making a STK4400 talk to both the Cray and IBM system. In the end, we supported

CMS (and other virtual machines) use Diagnose 8 to pass CP commands to CP for execution. Would those start going to Hercules instead? If so, that could cause some delightful explosions!! Bo Bolch

Hello Joe, I can see how VM, itself, can talk to Hercule via Diag 8, but how would a guest OS or CMS program? Wouldn't a Diag 8 in a virtual machine go to VM as a CP command instead of to Hercules.

Many 3480/3490/etc drives ("square tapes" to you IBMers ;)) have media changers on them. We have several of those at LSSM. I'm pretty sure they can change media under host control. Unless you're

Hello, I'm wondering if it is possible for a VM machine / CMS program to have Hercules change tapes? I'm working on the VM Backup idea. My thought is it would be great to automate the backup procedure

Actually I type (or set a PF key to) "CMS EXEC <filename> <arguments>" to run an editor macro. The macro must have an 'address' statement inside, I personally am tempted to write '/* REXX */ address

Martin, Thank you for the work you have done so far. I am really keen to have a play. I think you call it a “bleeding edge snapshot” or perhaps a “technology pre-view” but when you feel you

There are minor BREXX changes to support using the IBM FBLOCK interface to allow EXECs with filetype 'EE' . It's not so easy to beta test BREXX, because of the VMCE integration. It might be simpler to

Actually my binaries are bleeding edge - not beta quality, not alpha quality - should I call this zulu quality ? However such a binary would allow to demonstrate some changed behaviour and new
