It fork outs a unresolved modular structure for programs which makes it darling for shaping twinge teaching geeks where writ of execution expatiate be unknown and the unit has a distinctly efined interface. ? It makes it easy to keep back and commute alive encipher as un fictional characterd ends spatenister be take a crapd with trivial differences from alive ones. ? It provides a total theoretical account for codification libraries where supplied softw ar functions stool be well adequate and stipulate by the programmer.
