Inquires the maximum frame area.
CALL SWQRCT(WXMIN,WXMAX,WYMIN,WYMAX,FACT)
WXMIN (R) The X coordinate of the lower left-hand corner of a frame. (o) WXMAX (R) The X coordinate of the upper right-hand corner of a frame. (o) WYMIN (R) The Y coordinate of the lower left-hand corner of a frame. (o) WYMAX (R) The Y coordinate of the upper right-hand corner of a frame. (o) FACT (R) The unit length in the coordinate system. (cm) (o)
- (a)
- In a device where the size is not precisely known, such as displays, the frame size is considered to be about the size of an A4 sheet to set the FACT.
