Is there a way to process a source physical file with an RPG program processing all members (like a S/36 FROMLIBR procedure with *ALL)? If not, do I need a CL program to Override Database File (OVRDBF) and loop through the members?

From: Ernie Malaga To: Tim Phinney

The OVRDBF command accepts MBR(*ALL) to do precisely that. When you use MBR(*ALL), LR won't turn on until all records in all members have been processed. The INFDS for the file includes a field that contains the name of the member currently being processed. This field is in bytes 129-138 of the INFDS. Other than that, there's no separator between members (no record with blanks, nulls, x'FF' or whatever). Since this member identifier is in a data structure, you cannot determine when it changes using a control level indicator such as L1-you'll have to code your own.

I'm not sure in what order the members are processed. It would stand to reason that they are processed in the order in which they were added to the file (not alphabetically); check it out.
