Why do I receive COBOL FILE STATUS=92 FILE=MSRFMC a USPS db file

The USPS Reference files for consist of 8 files that are used by the software and 4 additional files that are not used by the software. The message - COBOL FILE STATUS=92 FILE=MSRFMC can if the files were not installed properly. 

Check the data base installation log for errors.
Check the data base log for the frecord count for each of the 8 db files used by MailStream Plus against the Greenbar report.
note: [Greenbar is the report that list the name of the 8 USPS Reference Files and their record count].
Check the job to make sure the DD statements are pointing to the correct data base files.
