I don't believe anyone has posted anything about calling FORTRAN code using ctypes. Why aren't you using f2py? -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco ------------------------------------------------------------------------- SF.net email is sponsored by: A Better Job is Waiting for You - Find it Now.
