This is compiler-dependent.  As I recall, Microsoft Fortran (to name one
example) has two types of character constants, one for use within Fortran and
one for use when interfacing with C.  The former has no accessible length
information or final delimiter stored with it at all, at least not that I
could find; the latter uses a C-style final null as a delimiter.  When you
program in Microsoft Fortran, you indicate that you want a C-style string by
appending a C to it after the final quote (e.g. 'foobar'C).  This is an
awkward solution to the problem, but it works.  Other compilers may not
provide any solution at all.
