Hello every one! I'm a new FORTRAN programmer and I 've gotten a confusion about some NAG library subprogram,the subprogram g05caf. I know that it is used to generate random numbers uniformly distributed in the range [0.0,1.0] and can be initialized by one of these two subroutines g05cbf or g05ccf.
Now what I'm confused about is that is this subprogram (g05caf) a function or subroutine because the text book that I'm reading name it a routine but deal with it as a function not subroutine (declared as a function). So if some one can explain this matter?
Note: you may like to have a look for my program, please open this link and refer to page number 48:
