The PREVENT routine prevents linking on fields named in the Field Comparison Routine Lists. It supersedes any other comparisons and forces a non-linking condition if the field specified agrees exactly with any positive matches in a set.
Note: This feature is only supported in window matching.
This routine can be used at any link level. It requires a positive action (pass or fail) through the matching patterns. Therefore, PREVENT can be used positively to force a match when any member of the group has the same value.
