Thats it's the text of the comment: > >"I have added a " LAM AR1,AR1,=F'1' " instruction near the start of the >User Service Routine and this has corrected the abend" The book for z/OS V1 R11 (ICSF FMID HCR7770, see http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CSFB2ZA0/5.3.2?SHELF=EZ2ZBK0H&DT=20091114130346 or http://preview.tinyurl.com/yeb9hnf ) and as I read it the book clearly states that the service exits run in cross-memory mode and must specify an ALET of 1 to access the parameters, which will be in the secondary address space. That same text is in the ICSF books at least as far back as z/OS V1 R7. APAR OA23636 addresses an error in Omegamon/XE where the exits it provides were not properly using the ALET of 1, and via that APAR they corrected their exits to provide that ALET. -- Walt ---------------------------------------------------------------------- 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
