When I am trying to repeat a record in VSAM file in edit mode using File-Aid, I am getting "command not found". How can I solve it, please advise.

What command are you trying to use?

You need to create it in a step running some program (e.g., *Sort) that writes to it.

13478 Firefox 50.1.0 on Ubuntu 14.04 LTS. I have to login each time. I don't see a pop-up with the Remember Me, just an ordinary page, and Remember Me is just a cruel trick. (it should have a "mouse-over" text which says, "gotcha' again, gotcha' last time, you can't even remember tha...

And Happy Hanukkah

It is out of courtesy to Anuj that we don't demand our usual billing rates

When I surfed to the board, the current quote was from the late Ken Olsen: "There is no reason anyone would want a computer in their home".

And he was right: the vast majority of people don't want computers, they want digital toasters that will supply them with cat videos.

Of course. The pseudo-code is:

It is perhaps also worth mentioning that Fujitsu (and Hitachi) mainframes are all 31-bit instruction machines, about 20 years behind System z architecture, and that Fujitsu has stated that it has no plans to upgrade to a 64-bit instruction set and operating system.

Why don't you just write the program to read a VB data set? We're not talking rocket science here.

10871 Hi, Sorry for the title but I could not post in the topic I posted http://www.zmainframes.com/viewtopic.php?f=28&t=2425. I searched the manuals but RC=4 can be set with NULLOUT but not 2. As we are trying to replace a program which sets up RC=2, so I have askedthe question. Assuming that ...

For a file, yes. For a data set, not so much (although it's still a non-trivial effort).

A COMP (COMP-4 and BINARY are synonyms) variable is binary (or hexadecimal, if you like), but further constrained by the decimal picture; a field with usage and picture S9(7) occupies a word (4 bytes), but will only accept numbers between (decimal) -9,999,999 and +9,999,999. The sign is the high-ord...

I suspect that people with as much experience as Mr. Sample and myself have for decades heard predictions that the newest whiz-bang technology would obsolete us mainframe dinosaurs in just a few years, you betcha! I would remind those inclined to make or listen to such predictions that dinosaurs rul...

Your post is incoherent; MVS runs on mainframes/

There's a small but significant base of PL/I out there (from which I have made part of my living for the last 20 years :D), but I don't think there are any new installations. The z/OS world seems to have decided that COBOL now has enough features that it can be used for any new development (and I do...

"Wall clock time" is just another way of saying "elapsed time" (you measure elapsed time with the clock on the wall, yes?)

First of all, realize that this a trick question; you'd seldom if ever want to do this in real life. Possible ways of doing this would be: Deleting all lines after STEP13, and either using the TSO SUBMIT command or writing the modified JCL to the internal reader, depending on the environment. Enclos...

You can do this using the ALTER command of IDCAMS. Whether you do it online or batch, and whether there is standard JCL, is of course dependent on your installation's standards. Note that this may, in real life, be a futile, even dangerous, effort. Usually data sets on DASD do not have an explicit e...

Well, no. But then I style myself a "software developer". What does that mean actually? I am an Electronics and Communication Engineer by education. It means that I have no degree, but have spent nearly forty years developing software -- designing, writing, and it for a variety of platfor...
