The documented return is via R14. The SVC 3 option is only available if the program is ONLY invoked via supervisor assisted linkage. If the routine can be invoked by CALL/BALR/BASR it must BR 14 - doing an SVC 3 in such a case will terminate the caller as well. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
