Mainframe, MVS and zOS Discussion

Don't make use of that. The behaviour is not documented, and could change at any future release of z/OS. That's a more important part of the answer than anything else. Yes, for winning bets. No for anything "useful".

The first SYSIN will be processed, where multiple exist. Although the /* will cause a //SYSIN DD * card to be generated, it will not affect the IDCAMS control cards in the first SYSIN. If at least one of the... now somewhat missing... blank lines exist in the actual JCL, that will cause the generati...

Paste the output from file two in the spool, the JESJCL.

When you say MAXCC=00, do you mean from the NOTIFY, or the output from IDCAMS, or both?

Paste the output from IDCAMS, the file three in the spool.

When you take data from another system, don't you do anything to check to check that you have a correct dataset? If you suddenly get an "empty" KSDS, how do you know you have the correct dataset? "VSAM initialisation" is not required for COBOL, or any other language. It's a bag-o...

The whole premise is rubbish. There is one "problematic" situation: a KSDS that is opened for input. If that KSDS has never contained data since it was DEFINEd, then you will get a file-status of 35 on the OPEN INPUT, and only OPEN INPUT, in COBOL. Now, if someone can explain the use of op...

I don't know how much IBM had on the internet in 1981, and don't think those little icon things were around until much, much later than that.

Looking at my browser history, it was there at least as long ago as 16 September 2013. The DeveloperWorks site has its own, non-bee.

Here's an example: //FIXPOS EXEC PGM=SORT //SYSOUT DD SYSOUT=* //SORTOUT DD SYSOUT=* //SYSIN DD * OPTION COPY INREC IFTHEN=(WHEN=INIT, OVERLAY=(51:7,44,JFY=(SHIFT=RIGHT))), IFTHEN=(WHEN=INIT, BUILD=(1,7,86,9)) //SORTIN DD * KEY1 ! ABCDE 1111-1111 KEY1 ! ABCDE FGH 1111-1112 It is the same principle f...

OPTION EQUALS INREC OVERLAY=(81:C'1') MERGE FIELDS=(81,1,CH,A) OUTREC BUILD=(1,80) That's an example with fixed-length 80-byte records. You can't concatenate VSAM datasets (unless you have something specific which can, like SAS), but MERGE takes multiple input datasets, which will be SORTINnn, when...

What SORT product do you use? Is the order of the data important?

What is the reason you want to use TRUNC(BIN) in batch? What is the reason you already use TRUNC(BIN) in CICS?

Why do you want to do this, specifically?

Well, it was very interesting on Sunday. The box standing in his basement, trying to get the power-supply working (in the end routed from the back to the front) and looking at the lights. Once powered up, and through the startup stuff, gets to OS/2 Warp, trying to work out how to change the IO confi...

And if it doesn't have to be an actual TSO command, WHO in SDSF has been pointed out to me.

It is live-streamed. If he is not there, there won't be anything to see.

Talk to your Storage group. They will be able to tell you.

Remember that your 3.13 means nothing, necessarily, to anyone else. The ISPF panels are customisable. So, what is it that your title of your 3.13?

OK, so now that flag is not mandatory, it is OK :-)

Yes, it was live and the next one will be live. Trouble is, although "noon" is self-explanatory, "tomorrow" isn't necessarily so, at 3am his time (8am mine). I caught the first hour, and the last half hour. The guy has a basement full of "projects", including a PDP-11, ...

Well, Board Index gives me no message, but since I have a flag, and I can't do anything to not have a flag, I don't think that's a very helpful response for me to make, but you did ask :-)

"Tomorrow", I don't know if 1 or 2 Feb, at noon Connor is streaming his install of Linux on this machine.

He had some fun and power problems last night my time (24:00 WET onwards).
