I am going to change all the F77 code to C++ some day.  I already have a 
heavily modified version of F2C that I have rewritten extensively and 
already moved several hundred subroutines from F77 to C++.  The biggest 
problem is the F77 write statements.  F2C fixes the other big problem 
automatically, the change of initial array index from one to zero.
