The IOFOCUS specifier indicates whether a particular unit is the active window in a QuickWin application. It takes the following form:
.TRUE. | Indicates the QuickWin child window is the active window |
.FALSE. | Indicates the QuickWin child window is not the active window |
If unit '*' is specified, the default is .FALSE.; otherwise, the default is .TRUE..
A value of .TRUE. causes a call to FOCUSQQ immediately before any READ, WRITE, or PRINT statement to that window. OUTTEXT, OUTGTEXT, or any other graphics routine call does not cause the focus to shift.
