How to determine if 20-bytes are required for the DPV Footnote codes in CODE-1 Plus

Products Affected:  CODE-1 Plus
When executing the batch driver, C1BM00, position 20-22 of the DPVOUT parameter requires an output location for 20-bytes to accommodate the DPV Footnote Codes.  It is unlikely there ever be more than three or four codes for a particular address so it should be acceptable to allow for 10 bytes if space is an issue.
