If PAGRTT = 0, 90, 180, or 270 degrees, then the following is true:
When these values (0, 90, 180, or 270) are specified for the PAGRTT parameter, the page size (PAGESIZE) parameter values are not automatically changed. You must specify the PAGESIZE parameter values with reference to the way the data is printed on the page. For example, using forms that are 8.5 inches wide by 11 inches long and printing at 6 lines per inch with a 10-pitch font:
The page reads top to bottom with the 8.5-inch side at the top (portrait orientation).
The page reads top to bottom with the 11-inch side at the top (landscape orientation).
