Mutual Calling Bettween C and FORTRAN Program

An interface method between programs written by C and FORTRAN computer languages is introdused in this paper. Using this method, both of C and FORTRAN programs can call the processes or functions written by the other computer language simply. When developing a system software package for a special function, we can comprehensively utilize the superiorly of two computer languages.This method can increase both of the program developing efficiency and program execution efficiency greatly.
