The definition of a constant (See CONSTANT DECLERATION STATEMENT under the
HELP menu in FB^3 is a ³static integer expression². I do not believe _nil$
is a valid constant ...consequently, I'm not sure how the compiler handles
it. 

There are times when passing an invalid argument (i.e. _nil) produces
unexplainable results and not necessarily an error message. I think that's
the case here.
