Now here's a question I should have asked initially because it sounds like you are having a type/size mismatch problem.

Do File1 and File2 have the same structure? By this I mean does each field in File1 have the same properties as its counterpart in FileB (same data type, same size, same offset position, etc.)?

The fields in each file have to match exactly.

Have you manually compared File1 against File2?

Booth,

Your sample is nearly identical to what I have. Difference is that without the e in the external position, SEU won't allow ExtName. Says keyword not allowed for a program described data structure. Put the 'e' there, and SEU is happy, compiler is happy. Just doesn't work right.

Define two data structures with the EXTNAME key word:

  D   wFileA       DS   EXTNAME(Format1)
  D   wFileB       DS   EXTNAME(Format2)

    C*       If chain is successful,
    C        if  wFileA = wFileB
    C*            delete record from file 2.

There is no need to load either DS.  That is done automatically

I have two files.  Different names, formats, and field names.

One is produced early in the day.

I need to remove records from the second file that are identical to
those in the first file.  Thus, second file only has new and changed
records.

I am stuck on how to set up a comparison of the entire record from
each file.  I know I have done this, many years ago, but my brain is
just too foggy.  I just don't want to have an IF with 90+ field
comparisons.

Logic is simple - read file 2, attempt to chain to file 1.  No chain
- a new record.  If chain is successful, compare the two records.  If
same, delete record from file 2.

I can't directly compare the record formats.  How do I define a
single field over each record?

I tried I-Specs - File name followed by single field name..

Dumb question.  Thanks for a nudge.
