That will work.  Unfortunately, it's not portable.

The file "udunits.inc" is a mixture of preprocessor directives and
Fortran statements.  It is designed to be included by the Fortran
preprocessor before the Fortran compiler ever sees the code.  This
was the only portable solution because the Fortran-77 Standard
doesn't specify any mechanism for including other files.  Various
compiler vendors have come up with various solutions, but none of
them are (or were, at least) portable.

Other Fortran programmers haven't had this issue because they
use preprocessor include directives rather than non-standard
Fortran include statements.

> I appreciate your time today, Yolande

Good luck.
