I am trying to find a pipe solution to the following problem: I have 2 files that have tags in them. I want to identify which tags are present in one of the files but not the other. A lookup would fill the bill nicely, except for the fact that there may be more than one occurrence of any given tag in either of the files. I want to do something akin to a lookup allmasters and delete one occurrence from the reference for each detail that matches. After all occurrences of a tag have been deleted from the reference, any remaining tags in the detail would be considered to be unmatched. Similarly, if not all masters were matched and deleted, those that remain would be deemed unmatched.
Is this something that can be done reasonably well. My brain has fogged over (too many meetings, I think) so I have not seen the simple solution that probably exists. Regards, Richard Schuh
