[AccessD] Strange compile error

Well, it's strange to me, anyway.

When I compile my code using the Debug|Compile menu options, I get no
errors.  I have one procedure, however, which throws a compile error -
not a runtime error - when I try to execute it.  The code for that
procedure is self-contained, with no calls to any other procedures.  I'm
scratching my head on this one.  I suspect some sort of corruption, but
don't know quite where to go looking or how to resolve.  

Can anybody suggest a solution - or a starting point?

Thanks!
