The PAGE directive controls the length and width of each listing page. Place the PAGE directive in the source file to control the format of the listing file produced during assembly.
Syntax
PAGE [operand-1][,operand-2] or PAGE +Remarks
Using PAGE + or the PAGE directive without an operand entries causes the printer to go to the top of the page and increases the page number by 1. The assembler normally takes this action only when a page is full.
The operand-1 entry specifies the actual number of lines that can be physically printed on the page; the default value is 66.
Use the operand-2 entry to control the width of the page. The page width without a specified number is 132.
Note: The PAGE directive does not set the printer to the desired line width. For proper formatting of the listing, initialize the printer to operate at a corresponding line width before printing the listing file.
