ResEdit will refuse to open a resource that is too big for it to manage 
(meaning it needs enough memory to hold the resource but also to display it).
From the looks of it, the latest ResEdit uses 3 List Manager lists to display
GNRL (which is what CODE opens up to anyway): the limitations on displaying
resources bigger than a certain size may also have something to do with 
limits in the List Manager.

As an aside, how about somebody taking a PD 68000 Disassembler and making it
the ResEdit Editor for CODE (this does not require recompilation of ResEdit--
yay Apple!).  I've long wanted to do this and have no time to.  But think of
the accolades from the development community!
