I refer to the lower case operands such as "yes" for sysstate amode64=yes. Maybe there's use of some assembly COMPAT option? There are also possibilities that the switch from amode 31 to amode 64 was not preceded by making sure to zero the high halves of all relevant registers (whatever those registers might be). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
