A job's authority to an object is resolved when the object is referenced, not at job initiation. The only security references that are resolved at job initiaion are those that are needed to initiate the job (JOBD, OUTQ, SBSD, Initial program, etc.) Each time an object is referenced during the course of a job, the job's authority is re-resolved. The classic example is a repetitive call to an external RPG program from a CL program. If the RPG ends with LR on, authority must be re-resolved for each call. (this contributes to the performance implications of ending a repitively called program with LR on). jte -- John Earl johnearl@toolnet.com PowerTech Toolworks 206-575-0711 PowerLock Network Security www.toolnet.com The 400 School www.400school.com -- +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To subscribe to this list send email to MIDRANGE-L-SUB@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
