Re: keyfield -- RPG400-L

Murali,

If I understand your question, you'll have to create a logical file over
the physical in order to do random I/O (ie. setll/read, chain). You can
order your physical file with an OPNQRYF but that really should be used
only for sequential processing. The access path (Keyfield(s)) has to exist
over the file for your RPG program to compile.


Good Luck,

Mark
