Hi,
  I think that I know what you mean. So, if I want to get the result with A 
> B > C, I should get A > B and B > C, respectively. And then, to combine 
these two results.

Would you tell me detail with step by step and what command I should type 
and how to type ? Or, have some reference to follow or to consult?

Thank you in advance!!
