Re: ECMODE on in every user directory entry
Joe, ? Its a CP command. CP commands work with nothing IPL d in the VM. In fact if CMS is IPLd and you do “SET MODE VM” you then need to re-ipl CMS because it resets the machine, as do some other CP commands ? However, its normal to have “OPTION ECMODE” on the directory for any VM that’s going to run MVS (or another OS that needs it). ? One may IPL CMS in a VM that’s going to run MVS or other OS so that you can tweak the configuration in ways that can’t be done in the directory. You do need to get creative, so if you issue a command that resets the machine, you need to have an IPL command on the console stack. ? For example, an EXEC with the following commands:- ? &CONTROL OFF &PUSH CP IPL 123 CP SET ECMODE ON ? Will set ECMODE ON and then IPL from device 123. ? Dave ? ?

Yes, Joe. But you missed the point.
If you need ECMODE on, would it be best to have it set in USER DIRECT??
OR
Is setting ECMODE ON (CP SET ECMODE ON), after logon, good enough??

Mark, ? Historically the answer is “it depends”.

Re: ECMODE on in every user directory entry
Joe, ? I didn’t mention that because we were talking about “normal” CMS users, and normal CMS users don’t use DAT., but yes for many Operating Systems you need ECMODE. You, or “a n other” will now tell me that CMS must use DAT and I will say “no it doesn’t”. A CMS machine always runs with DAT off and usually runs with a virtual BC mode PSW so DAT is irrelevant for CMS. Of course CP uses DAT but all this is hidden from CMS running in its own little virtual padded cell. It knows nothing of such things. Whenever it looks at its PSW, it generates a privilege exception and CP fakes nice, safe BC Mode PSW for it. So yes, if you are going to load an OS into a VM that needs DAT you need ECMODE but that’s not something most users do… .. you may also ask “how does CMS do IO to the high channel numbers if its running with a BC Mode PSW, well CMS does not issue SIO’s for DASD it uses DIAGNOSE 18 which is a synchronous interface so none of that messy interrupt stuff and channel masking is required. ?

Hi Gary, From what I see, the KICKS package has an install procedure provided by Dr. Ferland, so there is not really anything?to do for it except install it on the 1.1.2 master distribution copy of VM370CE.? What else would need to be done?
For me, including something in the VM370CE release implies that it is supported by that team. If you want something like KICKS, then it comes with a provision that any bugs would have to be fixed by the suppliers of that code.?

Yes you are. My problem is that I normally run the original Bob
system, when I do run VM/370 at all. I am interested in exploring this
better arrangement, and since I normally use a copy of PCOM to
interact with the system, that way.
"the original Bob system" ? Do you mean Bob Abele's original 3-pack system? On that one, I think only 01F is defined in DMKRIO as 3215 (for the operator virtual machine), so I guess a CP nucleus rebuild would be necessary. As for VM/370 CE, 004-00A are defined as 3215, with 009 as an alternate console. That leaves 004-008 and 00A (quite enough for me).
As for what you've commented on, question: Is this set in the configuration file for Hercules?
In the current configuration file vm370ce.conf of VM/370 CE, 00A is defined as a 1052 Typewriter terminal (3215); I added the same definition for 004-008 on my copy. Cheers, Rene FERLAND, Montreal
