Detailed Description

This macro finds any first date that is the first after a user defined gap (or the very first).

Remove duplicate records by ADate and PatId.
Compute gaps when &GAP. is not equal to 0.
- If &GAP. (washper) is 0, then all claims are deemed potential index dates with respect to own self.
- Initialize gap and assign previous ExpireDt.
- Reduce records to the first ADate per PatId.
Reapply gap against all claims (not just prior claim).
- If &GAP. (washper) is 0, then all claims meet gap requirement.
- If &GAP. (washper) is missing, then there are no prior claims as this has been already assessed.
