Re: Compare Files/Records

["Dan Bale" <dbale@xxxxxxxxxxx>]

John,

At first glance, I thought of CMPPFM, but that won't help you determine which
fields in a changed record have changed.  I can't think of any other system
utility to do what you'd like it to.  So, I'm guessing you'd have to write 500
programs.  Wait!  I'm thinking you may be able to write one program to generate
the code for those 500 programs.  Your program would take the DSPFFD outfile
data (could be from API, too), and generate the necessary code to do whatever
comparisons you want.  From your description, I can't see why this can't be
totally automated.

On the chance that someone will jump in with the perfect solution you're looking
for, I'll save my breath and wait to give more details of what I'm talking about
if nobody else comes up with anything.

Have you thought about using journaling for your validation test?  Still some
programming involved but I think this could be a one-program solution.  It would
also give you more details about when, who, and what.  And I just realized that
my original idea wouldn't handle adds and deletes very gracefully; you'd
probably have to do "matching records" (yechhh!).  Whereas journaling would
report adds and deletes nicely.

I need to compare about 500 files with 500 other files to see if any
records in the files are different and which fields have changed.  All
the files are externally described.  This is going to be used as part of
a software validation test for some conversions we are doing.  i.e.
convert the data-run the new software in parallel with the old
software.  Then convert the data to another library and the files should
be identical.  Something like CMPREC OLDFILE(TESTLIB1/FILE1)
NEWFILE(TESTLIB2/FILE1)

Obviously I would prefer to have the computer do all the work :)
