Any idea why Ironport classified this and one other message as spam?

Right. That's why I need the community to refresh my failed memory on using the LARL. The example was just to clarify what I was trying to accomplish. I dislike doing ORG instructions in code. And once reminded of LARL, I found the BRAS and BRASL instructions, if I'm only going to invoke the routine in a single place in my code. Please note that this is all for my personal edification. When I write code for work, I stick more to the "tried and true" instructions simply to avoid problems in the future with people who don't keep up with the new instructions (or even care any more). In any case, I am sure that IBM would love to make everybody go to Metal C instead of HLASM for the cases where an HLL such as C/C++, COBOL, PL/I, et al. cannot be used. > > Charles > > -- Money is the root of all evil.
