I really like this reduction. I previously used the hash to remove duplicate lines like below:

1: partnum=1003382553-M25,description=CNTFGL PUMP,quantity=1.0000,tags
+=PU-200
1: partnum=1003382553-M25,description=CNTFGL PUMP,quantity=1.0000,tags

Once I loaded this into a hash it reduced to the following:

1: partnum=1003382553-M25,description=CNTFGL PUMP,quantity=1.0000,tags
+=PU-200
559: partnum=2203505000,description=CONDUCTIVITY CELL,quantity=2.0000,
+tags=AE-100 AE-200

The current modification by scorpio17 adds the duplicates to gether, unfortunately.

Thanks for the help and the insight. I really appreciate it. Shawn Way
