        XTranslateCoordinates takes among other inputs the screen
number.  How does an application find the screen number?  For example,
I have the following line of code:

    XTranslateCoordinates( XtDisplay(widget), XtWindow(widget),
                    RootWindow( XtDisplay(widget), SCREEN_NUMBER),
                        0, 0, &shellx, &shelly, &w );

        I could hardcode SCREEN_NUMBER to be 0, but that doesn't seem
right.  I could use XtScreen to get at the screen pointer, but that
structure doesn't seem to have any field holding the screen number.
So, what am I missing?

PS      I know about XtTranslateCoords(), but it doesn't work (see next
posting).
