When you run a batch job in CODE-1 Plus, you can generate an uncoded records output file (C1BMNCO). This file contains records with valid ZIP Codes, but for some reason, the records did not match against the database. With a supplied user-exit, you can correct these records in the CODE-1 Plus Interactive screen. You display an uncoded record in the input area, correct the record, write the corrected record to a corrected output file, and then display the next uncoded record. For more information, refer to Correcting Uncoded Records.
