Since you are not executing in supervisor state and key 0, you need to specify LINKAGE=SYSTEM on the TIMEUSED macro.

It seems that the TIMEUSED macro, even as of z/os 2.5 level (01* STATUS = HBB77C0 ) when coded TIMEUSED STORADR=STIME generates the sequence TIMEUSED STORADR=STIME MACDATE 04/06/2005 LA 1,STIME AREA FOR RETURN OF TIME VALUE L 15,X'B4C'(0,0) SVT ADDRESS L 15,X'88'(0,15) ADDRESS OF SERVICE ROUTINE BASSM 14,15 which causes 0C4 on the L 15,X'B4C'(0,0) instruction. Does the TIMEUSED macro need updating to access the SVT the supported modern way? Thank you. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
