All of those six instructions actually pre-dated XA. I still have a (paper) copy of GA22- 7079-0 "IBM System/370 Assists for MVS" dated 1981, that includes descriptions of those six instruction and also FIX PAGE (E502) and six tracing instructions in the range E508 to E50D. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
