Re: Where can I learn how CMS is different ...
¿ªÔÆÌåÓýMatthew, Like many other enhancements DIAG58 arrived in the VM/370 extensions packages, SEPP and/or BSEPP as confirmed by ? ? which lists it as a feature included from BSEPP.? So it was available prior to VM/SP but only as a paid-for addition. There was also the EDGAR full screen editor which again was a separate product and which made use of DIAG58. I don¡¯t think it survives. I see VM/SP1 ?and SP2 had EDGAR compatibility code in XEDIT which was removed in SP3¡ ? ? ? Dave ? ? From: [email protected] <[email protected]> On Behalf Of Matthew T.

I am using XEDIT and its clones since VM/SP Release 1 up to today ... and counting. EE is great work by Dr. Hans-Walter Latz, but I miss a lot of features that XEDIT and KEDIT have. I have done massive extensions to EE to make it more XEDIT-compatible. A common infrastructure already exists for the SET / QUERY / EXTRACT / MODIFY / TRANSFER subcommands. Actually I am researching how EE could integrate with bREXX.
Having a macro capability powered by REXX is my first wish. The ingredients for the ALL macro will follow (SET SELECT, SET DISPLAY ...). Do you think it is desirable and feasable to have a decent subset of XEDIT as part of VM/370 CE ? |

Re: Another Time Zone Question (Sorta)
I have vague memories of needing to regen CP twice a year under VM/SP HPO 5 because you couldn't dynamically change the timezone.? We'd go in to IPL at 2 or 3 AM with the new nucleus just to change the timezone.? Fun.? Actually, since I was in college at the time, it *WAS* fun.? I definitely remember writing a CP command to change the *virtual machine* timezone under VM/ESA in the early 90s.? I suspect if you wanted to roll up your sleeves you could rather easily implement a CP SET TIMEZONE command under VM/370 because the data should be easy to overwrite in the nucleus.? However, I don't have a good feel for what that would do to a timer that spans the reset boundary -- if the system clock is in universal time and any timer deadlines are also in universal time it should be fairly safe (which is how I *think* it works).

Another Time Zone Question (Sorta)
Hello All,
I too, like Jay Maynard, am trying to specify the correct time zone for my location.? I know that DMKSYS is where it's specified, and I know that I want to change? 'SYSTIME ZONE=0,LOC=WEST,ID=GMT' to 'SYSTIME ZONE=5,LOC=WEST,ID=EDT'.? I also know the sequence number is 00220000. In my past life, I would simply edit DMKSYS ASSEMBLE and be on my way.? Now that I know that's the wrong way to do it, I don't quite know the right way using the E-disk for local mods. I see that MAINT MEMO B says to use VMSETUP CP to establish the search order.? OK, next I see that DMKLCL CNTRL E identifies where the local changes are (by way of filetype I presume).? ?DMKSYS AUXLCL E should contain an entry like 'LCLnnnDK xxx Change SYSTIME macro to reflect local time zone and ID'.? I don't know what values are supposed to be used for nnn and xxx.? What is the significance of DK? It also appears I need to create a file named 'LCLnnnDK MEMO E' which contains a lengthier description of the modification.? Finally, I assume another file is to be created named 'DMKSYS LCLnnnDK E' that contains: ,/ R 00220000 $ 00220000 1? ? ? ? ? ? ? ? ?mm/dd/yy? hh:mm:ss ? ? ? ? ?SYSTIME ZONE=5,LOC=WEST,ID=EDT? ? ? ? ?LCLnnnDK I'm guessing on the replace statement, I'm sure there's an IBM manual that describes how to code these update statements.? After all is done I simply
So, that's where I am.? I hope somebody can correct my assumptions and put me on the path to righteousness. (LOL) PS - Can I have two SYSTIME statements, one for EST and one for EDT?? Is the alternative to rebuild CP each time change? |

A sobering finding: my little tool produces essentially the same results as the already existing file VISTA IND$MAP Y2 on MNT19E. I feel like having reinvented the wheel for the seventh time. So for most users there is a very simple solution:? COPY VISTA IND$MAP Y2 DEFAULT IND$MAP A1? . Such a file does NOT exist on LCM+L's VM/SP 5, though their IND$FILE program is not IBM's ... it behaves EXACTLY like that from the MECAFF tool suite on VM/370 CE.
