How to use DFPORT

[j0zn]

Hi guys!
I would like to know how to use DFPORT,but I don't know how to use it.
Please write it with an example.

Thank you in advance

DFPORT has lots of functions - is there any particular one you wish to use? It has Bessel functions, date/time routines, file access, processes, sorting etc.

Also worth searching for PORTLIB if you have powerstation 4, or IFPORT on the later Intel compilers.

Example - sleep for 10 seconds

    program main
    use dfport

    implicit none

    print *, 'Sleeping for 10 seconds'
    call sleep(10)
    print *, 'Awake'

    end program main

To link you need libF90.lib and libPEPCF90.lib. You really need to tell us what you want to do with it. Nobody is going to invent a program with calls to over 50 functions ranging from Bessel functions to sorting, incorporating all the functions in dfport.

I am trying to calculate the integral of sin(x) from 0 to pi, using Monte Carlo. I want to call ran() or some rotine of the Numerical Recipes such as ran0.f90, ran1.f90 and so on.

If you are using Fortran 90, then why not just use the standard random number generator that comes with the compiler. That way, your programs will be portable across systems.

Have a look at
