You need to save it as a code resource.  There is a Mactutor article
(Sept. 88) on the particulars.

4D 1.0 does not use a true array structure, so you cannot pass an
array via an external. Version 2.0 (just released) does have that
capability.  call ACIUS and they will provide you with the glue routines
to access 4D's variable table.
