- Re: compiler flag question
I was thinking of having access via whatever preprocessor macro to
the active compiler options. As OpenMP does require a specific
macro to be present, so much the better :).
(If OP's compiler can't handle preprocessor macros, a solution
would be to include a library with dummy routines)

OpenMP standard requires the _OPENMP macro, so it seems cpp style
conditional compilation is at least a de facto requirement for OpenMP.
Conditional inclusion of omp functions is one of the most common uses of
_OPENMP. For example, I want to see in my report whether OpenMP is
active, with how many threads.

Ah, well preprocessor-defined macros ought to do what you want,

as there is no way to get that automatically. At least not standard.

EQUIVALENCE can avoid passing massive number of separated variables by

defines macros for all the separated variables. In this way, one will
not worry about situations like removing /adding a variable from/to

Yes. Exactly.
What I need is

(b) a subroutine that sync my variables to the latest status
Then, in all my functional subroutines, I can include the header file
and call the sync subroutine.
It works, :-)

Initially, you were talking about "general purpose programming", not

I guess this comes down to whether a program written in Fortran using

matter of definition of general purpose programming.

You can't do that in Fortran, or pretty much any

I am not so sure what you are trying to do, but...
If you have a large number of separate variables that you
need to pass around to many routines, you could put them in
a structure, though that requires features past Fortran 77.
For Fortran 77, you can EQUIVALENCE them to array elements,
and pass the array around. They must be the same type, though.
