In the following example, PROPPOS (4,12) puts the control 4 windows units horizontally, and 12 windows units vertically from the upper left-hand corner of the dialog. Or, to put it another way, 4 units to the left of the upper left-hand corner of the dialog, and 12 units down from that corner. PROPSIZE (150,40) makes the control 150 windows units wide and 40 windows units long.
PLACEMENT { PROPPOS(4,12) PROPSIZE(150,40) }
In the following example, LABELPOS puts the label for the control 4 windows units horizontally, and 2 windows units vertically from the upper left-hand corner of the dialog. The label, therefore, is the same distance from the edge of the dialog, but 10 windows units above the control.
