Using an older version of Mathematica, I was used to the system automatically beginning each notebook line with In[1]:=. All I did was enter the expression and press enter on the keyboard to evaluate the expression. Now however, using the default Mathematica Input (v.9), there is no initial In[1]:=. I enter the expression and press enter, and then the In[1]:= appears, followed by the value of the expression or the symbolic output. I would prefer to have each new line begin with a numbered In[]:=,

I would like to know if it is possible to get back the old behavior that I was familiar with? If so, what preferences do I need to set?

Perhaps you want the text-based interface? –  cormullion Jul 18 '13 at 22:17
Just out of curiosity: Why don't you like the standard behaviour? –  sebhofer Jul 18 '13 at 22:22
The behavior you describe is not new to the V9 Frontend. What was your previous version of Mathematica? –  m_goldberg Jul 19 '13 at 1:05
@Nasser Where exactly can I see the behaviour the OP described? –  sebhofer Jul 19 '13 at 11:16
@Nasser I seem to be blind. I just see a In[2]:=... but that just shows the behaviour of version 9. –  sebhofer Jul 19 '13 at 12:22
