─────The GETWSIZEQQ Function────────────────────────────────────────────────
 
     GETWSIZEQQ is defined as follows in FLIB.FI:
 
          INTERFACE TO INTEGER*2 FUNCTION GETWSIZEQQ(IUNIT,IREQ,WINFO)
          STRUCTURE /QWINFO/
              INTEGER*2 TYPE          ! request type
              INTEGER*2 X             ! x coordinate for upper left
              INTEGER*2 Y             ! y coordinate for upper left
              INTEGER*2 H             ! window height
              INTEGER*2 W             ! window width
          END STRUCTURE
          INTEGER*2 IUNIT
          INTEGER*2 IREQ
          RECORD /QWINFO/ WINFO
          END
 
     The IUNIT parameter specifies the window unit. The IREQ parameter
     specifies the kind of information requested. The following
     symbolic constants for IREQ are defined in FLIB.FD:
 
     Constant           Request
 
     QWIN$FRAMEMAX      Maximum size of frame window
     QWIN$FRAMECURR     Current size of frame window
     QWIN$CHILDMAX      Maximum size of child window
     QWIN$CHILDCURR     Current size of child window
 
     GETWSIZEQQ ignores the IUNIT parameter if IREQ specifies a frame
     window using QWIN$FRAMEMAX or QWIN$FRAMECURR.
 
     GETWSIZEQQ sets WINFO.X and WINFO.Y to the X and Y coordinates of
     the window's upper left corner. Depending on whether IREQ
     specifies the current or the maximum values, GETWSIZEQQ sets
     WINFO.H and WINFO.W to the current or the maximum height and
     width of the window's client area (the area within the frame).
 
     All positions and dimensions are expressed in units of a
     character height or width.
 
     GETWSIZEQQ returns zero on success and a nonzero value on
     failure.
