I don't think you can do it in OpenMP, I can discuss in the language
committee, but the definition of variable is:
"A named data storage block, for which the value can be defined and redefined
during
the execution of a program."
so I don't believe Fortran parameters are OpenMP variables.
Scalar Fortran parameters don't even have any data storage block associated
with them at all.
