I encountered this long ago with the first f90 compilers that I
used, but I think that modern compilers will scan through the file
and compile things in the right order regardless. Mostly out of
habit however, I still write code with the modules first, and USE
statements later. If there are compilers that require this, then
this module order is indeed more of a requirement than an esthetic
In any case, all of this is certainly compiler dependent and outside
the scope of the fortran language standard itself.
