        I am trying to use the macros ON_DISPLAY and OFF_DISPLAY as
described by the ROM kernel manual.  Following the example program
using the CWAIT and other copper macros, I included the appropriate
files, and made the following declaration:
  extern struct Custom custom;
as instructed.  Well, the file compiles ok, but the linker can't resolve
the extern custom structure.  Can someone tell me where this thing is
declared properly?  Or do I need to declare it myself, and in either case,
where is this thing suppose to be pointing?  (I am guessing that it is
a structure with information for the custom chips... am I way off?)
  I can't seem to resolve this, so I would greatly appreciate any input
from someone who has seen this before, or can see what I am doing wrong.

   Thanks for your time,

                          J. Norman Gee
