I need to compare the results of two different programs, as stored in the
same physical file. I have saved copies of both iterations, but am trying to
figure out how to do a field level comparison based on a keyed record join.
I'm trying to avoid an SQL with a select based on differences between fields
in the two files because there are 54 fields in the format.
TAATOOLs has a CMPDBF command, but it's an E1 file with null value fields.
In the case of nulls, I would want no comparison if both versions of the
field in question have null values.
Z/OS has a compare utility, but I can't find a match on the i. CMPPFM won't
work because the files are way too large.
Is there a way to do this without a massive SQL statement comparing at the
field level with 50 fields to compare for possible differences?

... what about journaling the file and compare the journaled images of the
related entries of your programm runs?
