System page
The maximum area in which graphics and text can be imaged is
called the “system page.”
Edgemarking To accommodate edgemarking, which is the placement of marks
along the edge of the physical page, the system page must be larger
than the physical page. The edgemarking capability is limited
because the system page boundaries correspond to the physical
page on at least two edges for all paper sizes.
Virtual page
The area chosen for printing is called the “virtual page” and may or
may not be as large as the system page. If you do not define its
dimensions explicitly, the virtual page dimensions are, by default, the
same as the sysgen-specified paper size or as the PAPER command
paper size.
If you explicitly define virtual page size (using the LANDSCAPE/
PORTRAIT command PAGE SIZE parameter), the defined area is
centered relative to the physical page dimensions.
The virtual page is assigned a landscape orientation by default, or
you can specify an orientation either with the LANDSCAPE/
PORTRAIT command or using the GRID command's FMTn option.
The upper left corner of the virtual page is called the “virtual page
origin.” The virtual page origin is also used to establish a form origin.
