-\item Suppose the following grammar for the WHILE-language:
-
-\begin{center}
-\begin{tabular}{lcl}
-$Stmt$ & $\rightarrow$ &  $\text{skip}$\\
-              & $|$ & $Id := AExp$\\
-              & $|$ & $\text{if}\; B\!Exp \;\text{then}\; Block \;\text{else}\; Block$\\

-$Stmts$ & $\rightarrow$ &  $Stmt \;\text{;}\; Stmts$\\

-$Block$ & $\rightarrow$ &  $\{ Stmts \}$\\
-                & $|$ & $Stmt$\medskip\\
-$AExp$ & $\rightarrow$ & $AExp + AExp$\\
-               & $|$ & $AExp * AExp$\\
