Right, that's what Algol-58 functions were, too. I think FORTRAN also has a construct like this, but I forget.

FORTRAN had both functions and subroutines. A function returned a value and was invoked in an expression (eg. S=SIN(A)). A subroutine was invoked by calling it (eg. CALL FOPEN(FNAME, PERMS)).

I should probably just Google this, but how did you define the functions?

    C     -------- START OF FUNCTION -------    
          INTEGER FUNCTION INCREMENT(I)
          INCREMENT=I+1
          RETURN
          END
    C     -------- END OF FUNCTION -------
