But BALR (as opposed to BAL) does not need a base register. If we're still talking about RACROUTE, I believe it should work just fine in a baseless program, assuming that (a) you write reentrant code and use L- and E-forms of the macro, and (b) you've included IEABRC to handle a few B and BNZ instructions that it generates. I can't comment on other system macros, though, as I haven't looked at them in this regard. -- Walt Farrell, CISSP IBM STSM, z/OS Security Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
