I am working on an XCMD that uses very large libraries.  If I tried to
link it all into one segment, it would be > 32K, & thus would not fit inside
a code resource.

I could possibly split up the libraries into XCMDs of their own and use
HyperCard callbacks to interface them at runtime.  Is there a more elegant
solution?

Also, I'm a little bit unclear on the restrictions LSC 2.15 places on
global variable usage.   I thought that LSC would reference globals off of
A4, but one part of the manual explicitly states that code resources cannot
have any global variables.  If this is the case, then what is LSC doing with
the string constants I use in my XCMD?  XCMDs *are* code resources, aren't
they?
