| how include in a fortran90 program a external library?
in C it was #include <...> in fortran?
can you write a example?

| #include in C does little more than make the prototypes visible to the
compiler
(and a bunch of related things, like macros and so on).
In Fortran I usually use a number of modules via the "use" statement.
That does more or less the same thing. Of course, you will need to
specify
the library at link time too.

Arjen

If it's in a source file, all you need is
INCLUDE '<name of source file>'
If it comes compiled with its own module file it would be
USE <name of module>
(note that USE isn't referencing a source file)
You need to read your compiler documentation on how to tell the compiler
where to find module files.
If it's an object code library, you need to read the compiler
documentation on how to link it in (these last two are compiler specific).
Catherine.
