<H3>

Determine if a system is using the large or small font setting.

</H3>

<P>

 The easiest way to do this is to read the <TT>PixelsPerInch</TT>

property of the global <TT>Screen</TT> object. If the value is 96, then the

system is set to small fonts. If <TT>PixelsPerInch</TT> is 120, then the

large font setting is in effect. It is possible for <TT>PixelsPerInch</TT> to be

neither 96 or 120 because the user can set the font scaling factor directly.
