Did you read over Section A.2.10 in _The Mathematica Book_ (Fourth
Edition)?  The information therein provides guidance on how input to
the kernel is processed on a per-line basis.  Note the last paragraph
which pertains to input within a notebook cell using StandardForm.

This section may be looked up by pasting the following expression in a
notebook and evaluating it.

FrontEndExecute[FrontEnd`HelpBrowserLookup["MainBook", "A.2.10"]]
