Title: Fast File Compare

If you need to write a program Matching record processing will do the job, it is by far the most efficient, look it up in the RPG Manual, otherwise use CMPPFM

Subject: Fast File Compare

I have 2 large files, with about 15 fields in each record. These 2 file have the same fields. I want to test these 2 files a record at a time to verify data integrity.

My question is this, what's the fastest way to compare these files.

I was going to read the (driver file) a record at a time, and chain to the equivalent record in the other file. and compare the records by comparing data structures that include the names of the all the fields in the 2 files.

is there a better/faster way?

Thanks, tim
