12. [I don't understand POINTER in Fortran very well.] Is it standard
to use rout, which has a pointer attribute, as an argument and then
ALLOCATE it inside your subroutine?

Yes - perfectly ordinary and standard. That does require that the dummy
argument also have the pointer attribute and that the procedure have an
explicit interface, but both of those conditions are met.

I doubt I'd have done this problem quite that way, but it is standard
and shouldn't cause problems.
