I am writing a program for the Mac that will display a window on the screen
that is either 80 columns by 24 lines or 80 by 20 lines, depending on how
big the screen is.  I know that I can call SysEnvirons to check whether I have
an SE, a II, etc., but this is not necessarily reliable (e.g. an SE/30 with
an additional big monitor).  Is there an easy way to check what size screen(s)
is attached?  I've done some hunting through Inside Mac in what I thought were
the obvious places, but I couldn't find what I was looking for. 

Any help anyone can give me will be greatly appreciated.


Thanks much,
jeff
