─────The IOFOCUS Parameter──────────────────────────────────────────────────
 
     The IOFOCUS parameter determines whether a window receives the
     focus when a READ or WRITE statement is executed. A typical
     use is
 
          OPEN(UNIT = 10, FILE = 'USER', IOFOCUS = .TRUE.)
 
     If the IOFOCUS value is .TRUE., the window receives focus prior
     to each READ or WRITE to that window. The value can be either a
     constant or an expression.
 
     NOTE: A run-time error results if the IOFOCUS parameter is
     used with a unit other than a QuickWin child window.
