Corrective action for the RECORD CONTAINS n CHARACTERS clause:

To maintain current behavior, remove the RECORD CONTAINS clauses. This change results in FILE1 and FILE2 both having variable-length records.

For maximum clarity, and for any new applications, use RECORD CONTAINS n CHARACTERS for fixed-length records and RECORD IS VARYING FROM integer-1 TO integer-2 for variable-length records. Avoid using RECORD CONTAINS n1 TO n2 CHARACTERS.
