- I take it you never use any NAG, IMSL or similar routines, then. If, for
- example, you want to call a general - purpose root finder, you will have
- to pass it the function to be solved, via an EXTERNAL argument. If you
- you want to communicate with that function, COMMON (which is indeed the
- only kind of global variable FORTRAN supports) is the only way to do it.
