Re: Update question

Its probably doing what it is supposed to be doing. I am suspicious that you may not be updating the fields you think you are updating? Or are updating with the wrong data. Is it possible that it is as simple as you are updating the update fields, not the Master file fields? (in other words, doing it backwards.) Just for fun, you could add a line of code updating one of the fields with a hardcoded value, like "123456' or "duh!" and see what happens. The results might point you in a direction that proves fruitful.

It's been a while since I've done an update program and I know I should know
the answer to this but I don't.

I have a program that reads an update file sequentially and writes to a
master file. After it reads a record from the update file, it chains out to
the master file. If no record was found with the same key it writes the
record to the master file with a WRITE. If a record was found with the same
key, it check 4 other fields to see if this is an exact duplicate. If it is
an exact duplicate it discards the record from the update file. If there
are difference in the 4 fields, it writes the update information by moving
the data to the master file's record and does an UPDAT. I should also
mention I've put code into the program to print the update record and the
master record when it finds one it is going to update.

I ran the program and it shows 200 records updated. I ran it again and it
again shows 200 records updated. It is apparently finding the discrepancies
but not really doing the update.

My question is this: once I find the differences, do I have to CHAIN again
to get the proper record in position to update?

TIA.
