FORTRAN to C interfacing help needed

[Bill Gieske]

I would like to interface FORTRAN routines to C routines.  How can I best go 
about this?  The only method I have found thus far is using FORTRAN common
and a C external data structure.  Works OK with integers, real (float) and
double precision.  Also works OK (almost) with the same data types as arrays.
Real and double don't completely match up.  Text is another story.  Any info
would be appreciated.
