FORTRAN 77 file calling a FORTRAN 95 file

[nonfamouswentz]

To start, I have two codes. One is written in FORTRAN 77 and the other in 95. Both codes have a main function that calls subroutine, that calls a subroutine, that calls a subroutine, and so on. My predicament is that in the middle of the FORTRAN 77 code, I need a value from the middle of the FORTRAN 95 code. The 77 code has static values (you run it, it returns a value), and the 95 code requires about 6 input variables to run that are needed to get that one value that I need.

How do I go about this? I would be glad to provide more information, including the codes (if someone would like to see them)

how do you go about what?

At it stands:
you run F95 program, get the value you need
then, you run F77 program

The answer is simple - you have to create a new program.
Make a subroutine with 6 inputs and 1 output from the F95 code.
Take the main program logic from the F77 code and call the subroutine on the place where you need it.
