LE does not always do the *** bit. Here is the same display from a subsequent S0C1. Tends to disprove the "all zeros" theory.

I'll ask the LE folks "why the asterisks". Might it mean "all 0"? But even if so, why bother not just displaying? If they have room in the display for 64-bit regs, why not just display them? Perhaps (for some strange reason) they don't capture 64-bit regs for AMODE 31 events (not that I'd like that answer) and the asterisks indicate "data not available". ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
