As it is the current example doesn't
work in release Erlang R14B02 (erts-5.8.3) [smp:2:2] [rq:2]
[async-threads:0]

There is a logic problem in one of the pattern matching.
"case This#dist_state.state of " tries to match 'true' which is never set. Instead it is set to a floating point number, which is used later to calculate the new value. I am suspecting that in the older releases any floating number was being cast into true?? But with the R14B02 release that I am working with the example doesn't work.

I fixed it in the attached code (I named it as module tut10), pls see the comments in attached file.

I named the file tut10.erl

I just started w./ erlang so can someone double check the code and the changes I made?


tut10.erl
