Parameter

 

n

   The number of blank lines needed. Values of 0 or less are not
   valid and n cannot exceed the number of lines of text allowed
   on a page (this would be the page-length value associated with
   the .PAGE SIZE command minus any header lines, any forced blank
   spaces after the header information, and any bottom of the page
   information specified by .LAYOUT 1, .LAYOUT 2, or .LAYOUT 3).
