Thanks,

Apparently, the current subroutine being compiled cannot have an interface in the module being USEd.

The Metcalf Fortran 95 book says that I can exempt the current subroutine from the USE by:

I just need a way to generalize the name and __FILE__ does not work.

If all of your general purpose subroutines and functions are in modules, you don't need interfaces for them (one of the advantages of modules).

I have 6,000 subroutines in 5,000 files.  All I did was put interfaces for about 2,600 of the subroutines into a single module.
