Determining which CODE-1 Plus output file will have General Delivery addresses with a +4 of 9999

Products Affected:  CODE-1 Plus
 
CODE-1 Plus provides an option to write addresses with ZIP+4's of 0000 or 9999 to the Coded output file (C1BMCOK) or Non-coded output file (C1BMNCO). This option is provided using position 71 of the Z4OUT parameter.  The default is to write the records to the Coded file, however, if you specify an N in position 71, the records will be written to the Non-coded file.
