Logical files let you define fields in the logical that combine multiple fields from the physical file. We use this function to build dates out of MM, DD, and YY fields.

You could merge 90+ fields into a single long field in an LF... and make it a key field...

Then write an AS/400 query over the LFs and find records in one file that don't have a matching record in the other file. Then swap the file names and run it again (or do the same thing in SQL...).
