Re: Storage Obtained By an SRB
Hi Michael, A search form more like this would have a much better chance of narrowing the hits down to what you are looking for. Most of the time, a good result will be on the first page of hits. srb subpool authorized Assembler Services guide v1r13 site:redbooks.ibm.com or srb subpool authorized Assembler Services guide v1r13 site: ibm.com substitute v1r13 with the release level you need the info for. Using :site limits the finds to the site that you specify . I use Google a lot, but whenever Google can't find something, I generally have great results at www.dogpile.com Please do give this a try, and please give us a better idea of what you are trying to accomplish.

There is no restriction on which subpools you can specify on STORAGE OBTAIN in SRB mode. There is an implicit and (and unfortunately, unenforceable) restriction that if you are writing any SRB mode code, you need to have a considerable amount of knowledge about how z/OS works.

One of the more useful functions of IBM-MAIN is to provide relative novices with a forum in which they can ask questions about functions that they are underqualified to implement. My problem with the OP's position is that he is aggressively defensive about his ignorance. His ignorance---We were all once in tht state---requires no defense, but there are protocols for asking other for help in dissipating it.

Re: Storage Obtained By an SRB
The generic answer to your question is that the alphabetically relevant Authorized Assembler Services Manual (almost) always specifies whether and under what circumstances an SRB routine can use the services of a particular macro, but there are often many detailed restrictions. There are, for example, some GETMAIN facilities than can be used by an SRB routine, but there are others than cannot. You are again asking a very general question without providing much context. Please make what you want to do clearer. Taking the time to do so now will get you better advice more quickly.
