Conclusions

Fortran-90 allows us to design a simple functional interface for SEPlib. The interface has been implemented in the sep module.

Depending on the compiler, the Fortran-90 interface may slow down the performance of I/O operations a little bit because of the function-call overhead. This slowdown is insignificant in comparison with the development time the new interface saves us. Moreover, separating the interface and the implementation allows us to work on improving both these parts independently.
