Remote procedure calls

[IO01036 at MAINE.BITNET]

  Hi !
  I would like to work on remote procedure calls under Ultrix/Unix . I haven't
  the faintest idea as how to go about it . The on line documentation does not
  help in any way .
  Does anybody have any references that I can look up and refer to ?
  Alternatively , are there any trivial ( not so trivial for me ) examples
  that anyone has and can mail them ? Your help is greatly appreciated .
  Thanx in anticipation ...
