>>comma is the sequencing operator.
>>The simple answer is that the comma operator in Erlang is
an infix sequencing operator, EXACTLY the same as the comma
operator in C or C++.  E1, E2, E3 has the effects of E1 then
E2 then E3 in that order and the value of E3.
   
  What does this mean?
Would some one please shed some light on it since I'm not a C guy?
An example maybe?
   
  >>C:  x > y ? e1, e2 : (e3, e4)
Erlang: if x > y -> e1, e2 ; true -> e3, e4 end
   
  I didn't understand this example.
Sorry guys but I didn't know anything in C language.
Thanks for help.
