...and the MBarHeight global is not supported under A/UX either...
Here's one way to get this to work, i.e. you expand the window to
cover the whole screen by setting the visRgn of the window to the
size of the screenBits.bounds. Note that this method is not permanent
because for instance dialogs will set the visRgn smaller than the 
screen bounds when they are called. So remember to restore the
visRgn.

Here's a bit of Pascal code that seems to do the trick, also with
A/UX 2.0:

Procedure FixIt;
{does the trick of expanding the window so it occupies the whole screen}

BEGIN
   MoveWindow( myWindow, ScreenBits.bounds.left,
               ScreenBits.bounds.top, TRUE );
   SizeWindow( myWindow,
               ScreenBits.bounds.right-ScreenBits.bounds.left,
               ScreenBits.bounds.bottom-ScreenBits.bounds.top,
               FALSE );
   showWindow( myWindow );
   setPort( myWindow );
   rectRgn( myWindow^.visRgn, ScreenBits.bounds );
   invalRect( ScreenBits.bounds );
END;

To restore the visRgn after calling up a dialog:

RectRgn( myWindow^.visRgn, ScreenBits.bounds );
InvalRect( ScreenBits.bounds );


And remember, the Apple User Interface Police don't like people
that create menu-less applications, unless it's a game, or 
presentation software, or a simstim deck.

Hope this helps,
