	The mailer at SCUBED.Arpa choked on this path.

Here's my response to your question; it may also be of general interest to
the net; the original question was about how to use screenBits.bounds from
an FKEY.

You can't use ScreenBits.bounds from a DA or FKEY, because code resources
(non-applications) can't use global variables. The solution is simply to
open a new GrafPort, and get its portRect -- for a newly opened grafPort
the portRect is the same as screenBits.bounds.

	After you get the bounds, you can close it again.

A future version of Lightspeed Pascal will probably support the use of global
variables from DA's and possibly other code resources.
