hello!

i got an take home final exam about fortran. i have to write a main-program wich uses the subroutine kendl2 from numerical recipes. the problem is, that i do not understand what kendl2 is for! Does anyone know, what happens in this subroutine? there are 3 variables wich should go out (intent(out)) to the main pr., but what kind of are they?

i really do not know how to construct a main program wich contains this subroutine!

thanks for help in advance,

many greetings, klaus
