Re: Is there a way in Fortran to designate an integer value as integer*8 ?

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++.

Modern Fortran might be the easier way, because a change can be done
incrementally, and this...

The biggest
problem is the F77 write statements.

... would not be an issue.  What features is modern Fortran missing that
you need C++ for?

F2C fixes the other big problem
automatically, the change of initial array index from one to zero.

If I remember correctly, it does so by issueing invalid C (or
C++), by using negative offsets from pointers.  Might work now,
might not work tomorrow.

But note the IIRC above.
