HLASM is interesting: its listing headers identify its PTF level. Presumably that is updated by replacing a CSECT. So each PTF must cite its immediate predecessor. The service graph is linear. But some customers insist, "Fix no problem other than the one I reported!" Fear of collateral damage results in regenerative maintenance phobia. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
