Which column in ADDRDF is considered the primary address line using the CODE-1 Plus batch driver

Products Affected:  CODE-1 Plus
The ADDRDF parameter is a required parameter and is used to define the location, length, and format of the addresses in the input record.

If you specify that your input address is in lines, you should define the lines in the order in which the USPS would like them to appear on a mailing label. In other words, the first line (left-most) is the least significant, and the last line (rightmost) is the most significant.

CODE-1 Plus will treat the last line you define (that actually contains data) as the primary address line unless you include the formatted City/State/ZIP in the last line.

The length of an address line cannot exceed 99 bytes.
