Field RA (RD)
Number and direction of the instances of a form in a display.
RA is the number of repeats left-to-right across the display; RD is the number of repeats top-to-bottom down the display. The total number of instances of a particular form is the product of RA and RD (RA*RD).
An integer (1 to 999)
If RA or RD is not specified, 1 is used.
When a form is repeated in a display, each instance of the form is assigned a subscript. The subscripts always begin at 1. If LoadOrder is row-major, then subscripts are assigned from left to right and top to bottom; otherwise, they are assigned from top to bottom and left to right.
