GRP7021

The Factor 1 entry (positions 18-27) is not the same type as the Factor 2 entry (positions 33-42), or the Factor 1 entry is not the same length as the Factor 2 entry; the specification is ignored.

Define the fields in Factor 1 and Factor 2 so that they are the same type (both numeric, or character) and the same length. Compile again.
