Function 48, subfunction 5 - get screen working area.
Parameters:
- eax = 48 - function number
- ebx = 5 - subfunction number
Returned value:
- eax = [left]*65536 + [right]
- ebx = [top]*65536 + [bottom]
Remarks:
- The screen working area defines position and coordinates of
a maximized window.
- The screen working area in view of normal work is all screen
without system panel (the application '@panel').
- (left,top) are coordinates of the left upper corner,
(right,bottom) are coordinates of the right lower one.
Thus the size of working area on x axis can be calculated by
formula right-left+1, on y axis - by formula bottom-right+1.
- See also function 14,
to get sizes of all screen.
- There is a pair function to set working area - subfunction 6.
