Probably. I think you have a procedure named INTERPOL somewhere
in your path that is being compiled before the IDL *function* of
the same name is being compiled.
Try this:
IDL> .Compile interpol
IDL> Help, /source
If the INTERPOL is not the one in the IDL lib directory, then you
are finding some other one, which is not the one you want. To fix
the problem, put the IDL lib directory first on your path.
Cheers,
David
