The DEFINE/FORM command qualifier /LENGTH specifies the physi-
cal length of a form page in lines:
$ DEFINE/FORM/LENGTH= n
The default page length is 66 lines, which assumes a standard page
length of 11" with 6 lines of print per inch. The value for n must be a
positive integer greater than 0 and less than 255.
The DEFINE/FORM command qualifier /MARGIN specifies one or
more of the four margin options:
$ DEFINE/FORM/MARGIN=( option [,....])
Option
Purpose
BOTTOM= n
Specifies the number of blank lines to leave between the end
of the print image on a page and the end of the physical
sheet of paper. The n parameter must be a positive integer
that is less than the /LENGTH parameter. The default value
is 6, which generally means a 1" bottom margin.
LEFT= n
Specifies the number of columns to be left blank between
the leftmost printing position and the actual print image area.
The n parameter must be a positive integer between 0 and
the value of the /WIDTH parameter. The default value is 0,
which means that the print image area starts as far to the left
of the paper as the printer can go.
