Using CANDE, open the CODES file (*NGEN28SYS/CODES).

From the first group of records, insert a new record after record 014, starting at column 21. For example:

 00001400		014 		bldcblink
					019 		bldcwidth
 00001500 	015 		bldcoc#

Find the group of records that identify printer models.

Specify a new line width for your printer model, by inserting a new record in sequence, with 019 starting in column 21. (Values for existing records might appear starting in column 24.) For example:

 00009400myprinter 		01127D3(*8N3)6B(*8N3)5B 		bldcforms1
 00009300myprinter 		012 									bldcforms2
 			  myprinter 		019llll 		bldcwidth
 00009500nextptr 			000PRINTER 							01281024
 00009600nextptr 			00127A3F15B 						bldcbig

Here llll is a four-digit printer line width. Any values greater than 1023 defaults to 1023. (You should use a large value to avoid any line feed characters being omitted.)

Repeat this for all printer models that you want to specify line widths for.

Save the CODES file. (If you are using CANDE with a usercode, you need to save the file with a temporary name, then copy it as the original name.)

Reload the CODES file into the NGEN28/1/LIBRARY by using the mix AX Load CODES command.
