Re: Reading a joined file in RPG

["Russell Conerly" <rconerly@xxxxxxxxxxx>]

If I'm understanding your query correctly, it sounds as if you are trying
to "externalize" the database into separate physical files and group them
under one logical in order for the existing program(s) to still process
them as program described.

If this is the case you may want to look at using a record format selector
program.  This program is specified on the CRTLF command.  I've attached
the link to the particular manual...IBM Database programming guide

I hope this is what your looking for.
