Mainframe, MVS and zOS Discussion

What medium are we talking about?

If there are no static links.

Robert, you should know better than to write this*. This is nor practical.

Obsoleting a program should not be done on the basis of how many times it's been run. Is your lead planning to delete the year-end processing on the theory that it's only been run a few dozen times and is therefore not very useful?

The answer is "yes". As both Dr. Sorichetti and Mr. Sample have said, however, it's a stupid and wasteful thing to do.

So are you saying that even if we change the JOB to have multiple steps, it will still be same for the int...

COMP-3 is not eight bytes; it is ROUND((number-of-digits+1)/2) bytes.

To reiterate what Mr. Sample said:

Again noting my lack of recent experience in C, I do not believe that there is any real equivalent to #ifdef in the PL/I preprocessor. For certain limited functionality you could use the %SYSPARM function and the %IF statement.

Interviewers are often wrong.

Note there is no connection between program and plan; specifying a plan name does not indicate what program should use it.

It's been a couple of decades since I wrote any C, so I may not properly understand what you're looking for, but I think you want the LOCATION function.

I cannot find the link to new posts.

You can get the creation date of a data set via the LISTDSI function of Rexx, or by parsing the output of LISTCAT. Other senpai may have other suggestions. You cannot, however, do it through JCL alone.

Unsurprising, as the fine manual indicates that EVEN and ONLY are not available to the COND parameter on the JOB statement, but only on the EXEC statement.

Have your scheduler release the job every 15 minutes.

No. Depending on your needs, you may wish to use the Rexx time function.

The Language Reference does not state that KEYTO can be used with WRITE, but rather with READ; see page 299.

Yes, this can trivially be done. However, I would question if 80-85% of their time is really spent doing this (if so, it speaks very poorly for their competence) and if they really run the same queries each time (again, if so, it speaks very poorly for their competence).
