I'm not sure this is what you are looking for, but Birgitta pointed me to the VALIDATE_DATA_FILE function or the use of the SQL Except when I asked how to compare two copies of a file when there could be differences in dozens of fields. The SQL did a great job of showing me all cases where the two files did not match. Unfortunately, I wasn't (and still aren't) on a release that supported the function referenced.

Look for her post from June 20th, 2023 entitled RE: Comparing Two Copies of a Physical File:
Have you had a look at the VALIDATE_DATA_FILE Table Function within the
SYSTOOLS Schema?
https://www.ibm.com/docs/en/i/7.5?topic=us-validate-data-validate-data-file-
validate-data-library-table-functions

Otherwise you may run the following query ... if it does not return any row
both tables are identical:

(Select * from Table1
Except
Select * from Table2)
Union
(Select * From Table2
Except
Select * From Table1);
