Re: Secondary Keys

Can I assume by "secondary file" that you are currently using
primary/secondary files with matching record logic?

If you replaced this with a join logical, you'd only have one file on
your F-spec to read, instead of two like you have with primary/secondary
file logic.   All the fields you need from your PFs are combined into
one record.   The records can be keyed by fields from either file or
both, and this is set up in your DDS for the join logical file.

You might also consider simply sorting the data in your subfile, rather 
than re-reading the file each time.   If its a small, multiple-page-load,
subfile, this could be faster and save you a lot of anguish.  Of course,
it wouldn't work on a single-page-load subfile, and might not be 
practical on a large subfile.
