After. But before the LINK'ed to program gets control. An SVRB is never freed before the SVC routine is done (and part of the "doing" of the LINK SVC routine is to queue the PRB). >In fact (unless this has been rewritten without my consent) >programs executing as a result of EXEC PGM= are (normally?) invoked >via LINK, and they run under a PRB (or used to). If by "programs executing as a result" was meant the program identified by EXEC PGM=, "not in fact". That program gets control via ATTACH. It does run under a PRB.
