This variable is used on character-based hosts to specify the color and video
attributes of the characters that comprise the border (box) around an inactive
floating window. INACTIVE_BORDER_ COLOR can be set to a variety of numeric values that express combinations of
color and video attributes.
If INACTIVE_BORDER_COLOR is set to "0", the inactive window's border is drawn with the colors and
video attributes specified in the COBOL program when the window is first
created. The default value is "0".
