   Hi,
	This is another in a series of questions orignated from my secretary.
   Within LaTeX, is it possible to change the left margin temporarily and
   still retain the option (within this new smaller page) to use eqnarray,
   array, etc.?  This comes up when writing proofs of results, where one says

   Thm  blah blaah .....
   Proof:
   (==>) proof proof proof proof proof proof proof proof proof proof 
	 proof proof proof proof proof proof proof proof proof proof proof

		eqnarray stuff
	proof proof proof proof proof proof proof proof proof proof  QED

   (<==) proof proof proof proof proof proof proof proof proof proof 
	 proof proof proof proof 

	       array stuff                                       QED

[...]

   BTW  A related desire is to be able to hfill within the  eqnarray* or array
	environments.    This was implicitly done in my above proof, where
	QED was on the same line as array stuff.



% Try the following scheme:


Thm  blah blaah .....

\noindent%
Proof:
\begin{itemize}
  \item [($\Rightarrow$)]
	proof proof proof proof proof proof proof proof proof proof 
	proof proof proof proof proof proof proof proof proof proof proof
       	\begin{eqnarray}
	  eqnarray & stuff    & 	\\
	  more     & eqnarray & stuff
	\end{eqnarray}
	proof proof proof proof proof proof proof proof proof proof
	\hfill QED
  \item [($\Leftarrow$)]
	proof proof proof proof proof proof proof proof proof proof 
	proof proof proof proof 

	\hfill\(
	\begin{array}{cc}
	 array & stuff 
	\end{array}
	\)
	\hfill QED
\end{itemize}

\hfill within array seems to be hard. If you really need something
that looks like that encapsulate the array in a minipage and \hfill
after the minipage.
