I have a requirement to to figure out a way to execute an edited Rexx exec from ISPF Edit. Is this possible to do without saving? The issue is that we need to make changes, execute, make more changes, execute, etc. It would be nice if this could be done with out needed to create and maintain multiple versions.

Thanks very much.

Do it the standard way: make a copy and play with the copy.

Thanks Nic. Seems like there isn't a way to do what I'm asking.

So the steps would be:
1. Make a copy
2. Edit the copy
3. Save the copy
4. Execute the copy
5. Delete the copy.
6. Repeat.

Is there a way to streamline this? For instance could we make the edits and then run an ISPF Edit Macro to save as a temp file and execute? The SAVE command doesn't seem to have the option to save to a temp file.

Thanks

I would not edit the production data set itself because other people might be using it. You are playing with fire.

You need to look at your SYSPROC or SYSEXEC concatenation. You should have a private data set concatenated ahead of your production data set.

The order should be:
1. Copy member from production to private data set
2. Edit the copy
3. Save the copy
4. Execute the copy
5.
6. Repeat 2-4

When you are satisfied with your changes:
1. compare with the production data set member to make sure someone else has not made changes at the same time as you. It happens.
2. optional: have a team member review your changes.
3. rename the old production member so you have a backup. (It is easier to back out your defect-laden changes - spoken from experience)
4. MOVE member from private to production data set.

Of course, it would be better if you used software control program like SCLM to manage all of this.

Your situation is not clear, but in a similar situation, I learned to use two separate userids that are logged on simultaneously.
1. On one userid, I was editing the macro (and saving)
2. On the second userid, I could edit the target data and could execute the macro. This userid needs to have the macro in the SYSPROC or SYSEXEC concatenation.

Thanks Pedro. I'm familiar with our SYSPROC concatenation and have created/edited a few execs. I'm also familiar with production code precautions. In this case, it's not that sensitive.

Would the following make sense or be possible? I'm trying to limit the user steps as much as possible.

1. Rexx Exec executed from member list makes temporary copy
2. Rexx Exec opens copy in Edit mode.
3. User makes edits and saves copy
4. Rexx Exec continues and executes saved copy

Thanks

I am not sure that your current plan is feasible...

You can start the editor, but your rexx exec does not continue executing until the editor ends.

Your earlier comments said you were editing an ISPF editor macro. It can be done, but executing the macro is another level of complexity that you need to consider.

Some suggestions:
- make the temporary copy only if it does not already exist.

- make one exec that makes the copy and launches the editor

- make a second exec that executes the copy. Actually, it could be the same exec if you have logic to keep track of the status.

Thanks again Pedro. In step 4, there is no further editing to be done. The saved copy just needs to be executed. The saved copy is another edit macro but the first exec will have done its job and can exit.

I like your idea of trying to combine this exec with the other exec. Will ponder this some more.

I also found a REPLACE command. From the manual:

The REPLACE primary command replaces a sequential data set, member of a partitioned data set, or z/OSĀ® UNIX file with data you are editing. If a member or z/OS UNIX file you want to replace does not exist, the editor creates it. The editor cannot create a new sequential data set.

This looks like it might do what I need. Will try.

Flucking 'ell, you're telling what needs to be done. It shouldn't be very hard to actually write an exec or even an edit macro to just this. It would probably take me longer to start up my z/OS system than writing the code...

And why the effing 'ell can't you make all changes in one go?

Maybe next time you should first explain the (il)logic behind such a "requirement", so that we don't have to waste our time figuring out what you want!

Actually I don't find that idea stupid at all, I have been doing that for years.

This link should work:
harders-jensen.com/wjtech/zprograms.html
I had been using the URL tag, must have done something wrong.

Thanks very much Willy. I will need to study this more but after a quick review, it looks like it will work very well for my purposes. Thanks very much for posting.

I have written some editor macros that were hundreds of lines long. Like any other program, it might take some bit of debugging to get to run to your satisfaction.
