The external database Ref is a long (unsigned I think) in C. You have to
be careful with these because they combine two word parts that let the
system know where the data is located. If you're just using them as handles
(the way they should be used) then the long datatype is what you're looking
for. PDC/Turbo Prolog has a Professional User's Guide that details using
the external database with C but they point out that some of the predicates
can cause problems (presumably the nondeterministic ones, especially).
