Larry, I don't know about Endevor, or how it stores JCL. We've done mass updates to JCL via batch (with a REXX, as you stated) and that has been extremely effective. Our ESP processing system picked up the changes to the master JCL libraries on it's next schedule build. Does Endevor work that way? If it's just PDS/PDSE members you're updating this should be a snap.
