OPEN: IOFOCUS Specifier (W*S)

The IOFOCUS specifier indicates whether a particular unit is the active window in a QuickWin application. It takes the following form:

IOFOCUS = iof

iof	Is a scalar default logical expression that evaluates to one of the following values: .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.
