Should I convert FORTRAN code to C?

Real 2-d arrays turn into pointer-to-array, not pointer-to-pointer.  If
you have one of these dynamically-allocated arrays that have been
bandied about, which is really an array of pointers to blocks of data,
*that* is pointer-to-pointer.

It's both more and less powerful.  To put it another way, FORTRAN's
COMPLEX data type is NOT an adequate replacement for the ability to
define custom data types.

Sure it does, it just takes a little more code than the FORTRAN
example.  But that's a strawman anyway.  For every such example, I can
write one in C that FORTRAN similarly "can't" do.
