I believe it replaces the existing IDR record with a "empty" one
<snip> If you relink as the AMA120I suggests/instructs the Binder adds another (empty) IDR record so you can use the IDENTIFY statement (think this is automatic although it may be triggered by supplying a Binder command to add more IDR Space). As you note, this allows you to track what ZAPs have been installed. If I remember IDR is ID Record. There are IDR records for each CSECT in the Load Module (they come from the Assembler) so you can see what the assembly date of the CSECT is (there is only one for the last linkedit). </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
