I haven't found it. >>way to do this succinctly: by using concatenation to construct the necessary XPL code "on the fly" That has been my approach, but for the longest time, although I constructed such code, I couldn't find a way to reliably execute the code I constructed. Got it into (say) S/G 03, <PV03> doesn't execute the code, it streams it into wherever the cursor is on screen. It gets into 03 by some statement like <SX03,<IS10>+<IS11>+<IS12>>, but 'SX' is not 'SU', and no subroutine is defined. Gotta get S/G 03 marked as a subroutine, rather then just string data, and there didn't seem to be an easy way to do that in Xy3 plus. Xy4 may be different, and that seems to be where you were working. I think I finally figured out a way to reliably make that happen with Xy3, but I'm curious as to what you would say as to how that problem is generally solved. Wally Bass
