The binder default is REUS=NONE. There's no option to tell the binder to set it based on the inputs (like might be called "REUS=MIN").
The existing attributes, to the extent they are available to the binder, are only used to determine if there is a conflict with a specified reusability. If you have an existing program module in a library then you can use INCLUDE -ATTR to have the binder set the reusability to that of the included module. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
