Toggle High Intensity in a show command

[Mike]

Can someone please help me out with the correct syntax to get the high 
intensity to work in a show command?

This is what I am trying but regardless of using the \i or not using \i 
it shows the exact same color.

show ("21","16") "\b0\i\f5Select Department"

and this is all the documentation says without even one example to show 
you where in the show command it's supposed to go, that took me a while...

"Show Codes (Color only):
    \I      Toggles high intensity
    \Bn     Sets background color
    \Fn     Sets foreground color
    \Ann    Sets attribute (background+foreground)
    \C      Characters only"

Windows 2008 Server, Filepro 5.0.09 DN9

Any help is greatly appreciated,
Mike
