Good thought, but I don't assume 8. I do an IPK/STC R2 during initialization. The value in my SPKA register is FFFFFFF80 (I do an LB so the high bit gets propagated) so the IPK is working plausibly at least. (PooP says the high bits are ignored.)

There are indicators in the books that programs can run in keys 9 through 15. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
