You should at the very least be thinking about recovery as you write new code. You can't really build the entire foundation first, since you don't know in advance everything you will have to free up or undo in your recovery routine until you have written the main code that acquires or does it. Write notes to yourself that you need to release such-and-such a resource later on, if ending normally or abnormally. Resources include CSA/ECSA acquired, locks held, and pretty much anything for which your code must be authorized to obtain or to do.

It isn't mentioned in connection with SRB's, but it may be supposed to be obvious. This seems like a good place to point out that you should start trying to find out these answers yourself before asking the IBM-MAIN world to help you with each problem you encounter. Look in the Authorized System Services Guide (but not Reference) and read the section on program recovery. That book also has a section on SRBs. You should read all of both sections before you try anything else and before you ask us more questions. Get the CBT tape if you don't already have it, and scan it for SRB routines that you can study and find out what others have done, then go read the IBM doc on what system services they are using (like IEAMSCHD, WAIT, POST, SETFRR, etc.). I am not trying to be a jerk, but sooner or later you will have to debug something and IBM-MAIN will not be around, or else you won't be able to wait for an answer from someone else. Ask us to explain something you find in the book but do not yet understand. Read up on the operator command CHNGDUMP in the appropriate IBM book. It will tell you how to get CSA, et al., dumped. A large part of the education we all had to go through was to learn in which IBM book the question was answered. Almost all questions are answered in some IBM book.

Why don't I see my CSA storage in the dump?
I'm reading the Initialization and Tuning Guide about CSA storage. I'm not absolutely sure, but I'm thinking that any data my SRB gets it can squirrel it away in the CSA for my main program to deal with later. Problem is that I don't see that data in the SYSUDUMP. I get it this way: STORAGE OBTAIN LENGTH=xxx,SP=227 But there is nothing at that address in the dump and the VIRTUAL STORAGE section of the dump doesn't list that subpool. So I'm wondering if someone can give me hints about what I've gotten wrong. It'll be important to read that area of data to debug things.

Re: Why don't I see my CSA storage in the dump?
Problem is that I don't see that data in the SYSUDUMP. SYSUDUMP, IIRC, only dumps user areas. You need a SYSMDUMP (?), COM DUMP, or better.

Re: Why don't I see my CSA storage in the dump?
Lindy, What you really want to do is write an FRR routine for your SRB which will do all of this for you by creating a system dump. Since CSA/ECSA can be very large, create a list of storage addresses which include your CSA/ECSA to be dumped. Additionally, now that you have obtained CSA/ECSA, you need to learn to be a responsible z/OS citizen and free your CSA/ECSA storage after your program terminates, either normally or abnormally. Since you have acquired a resource, you need to issue a RESMGR EOT and EOM routines to clean up in all cases.

Re: Why don't I see my CSA storage in the dump?
Thank you Tom. This really reinforces what I had in mind. I thought that instead of going wild and doing a bunch of SRB code that I should build the foundation first, meaning all the error recovery and so on. It may not be as fun, but I think in the long run it will make things easier. Thanks for the RESMGR hint, too. Now I see it in the doc (hidden away). Another thing I think I have to consider (the list is growing) is making my main program wait for the SRB to finish. I don't know if this has anything to do with it, but the WTO's that came out were like this: Program Starting Program Ending Beginning of SRB End of SRB That's a bit out of the order. Could have had something to do with my machine going into spin cycle. I won't be such a pain on IBM-MAIN after tomorrow since my vacation is over and real work will get into the way of my latest hobby.
