c         this function subprogram is called by the main program fm080.
c     the type declaration is implicit real.
c     the function dummy arguments are both integer and real. dummy
c     arguments idon01, iddn2a and iddn3a are incremented by 10, 20 and
c     40 respectively before control is returned to the main program.
c     the value of the function returned to the referencing program
c     will be the sum of the actual arguments as passed to the
c     subprogram ff083.
c         dummy argument iddn2a corresponds to an array-name in the
c     actual argument of the main program.  dummy argument iddn3a
c     corresponds to an array-element-name in the actual argument of the
c     main program.  dummy argument idon02  corresponds to an expression
c     containing variables,arithmetic operators and constants in the
c     actual argument of the main program.
