If your recovery routine switches from AMODE31 to AMODE64, why would it need to branch to 64 bit storage? If you're talking about the SETRP, then you would need to set the SDWA to retry using the 64 bit registers in SDWARC4. >For sdwaec2 I would have to find it in the linkage stack Since you are searching the linkage stack in reverse, you might want to keep in mind that percolation could have destroyed the relevant linkage stack entry. >How would I know I have the right entry maybe by comparing the lower half of >the registers Will a SDWAEC2 ever be above the bar? If I remember correctly, above the bar storage is obtained in large chunks (MB's). Rarely will a non-LE programming language create load modules large enough that makes above the bar a consideration. I suspect it's a safe bet that SDWAEC2 won't be above the bar but you could warn users of your diagnositc routines that you make this assumption and how you handle it. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
