Yes, there IS a way to use multiple resource files in an application.
Unfortunately, it involves a trick using undocumented GEM variables.
The technique was demonstrated in a German ST journal, but I don't
remember which one and when.

Apparently, GEM stores the root of the resource tree in an entry in
the  global[]  array, which can be found via the GEM parameter block
passed on an AES call. You should be able to use more than one resource
file if you do the following:

	1.	rsrc_load() the first file
	2.	rsrc_gaddr() all your pointers
	3.	save the global[] entry in a variable
	4.	repeat 1. and 2. for the second file

When your program is finished, you  rsrc_free()  the resources loaded
from the second file, restore the pointer saved in step 3, and repeat
the  rsrc_free()  call for the resources from the first file.

So. What is that entry in  global[]  that I've been talking about ?
Sorry, but I don't remember, and I can't check now because my ST is
5000 miles away from me at the moment. I suggest you look in some
recent book on GEM.

			Hoping to have helped you.
