Huh. Have I been doing this wrong? I've got some *old* (DSORG=PO) code that, after READ/CHECK, follows DECB->IOB and uses the residual count at IOBCSW+5. (Not my invention. I'm sure I lifted that code from someone else, probably Dave Phillips, back in the day.) -- David Andrews A. Duda & Sons, Inc.
