+To examine the \$internalHistoryTable use the following line
+\begin{verbatim}
+  )lisp |$internalHistoryTable|
+\end{verbatim}
+We need to pick out first member of internalHistoryTable and then pick out
+the element with \% as first element. Here is an example showing just
+the first element of the list, which correponds to the last command.
+
+Note that the last command does not necessarily correspond to the last
+element of the first element of \$internalHistoryTable as it is in this
+example.
+\begin{verbatim}
+   (
+    (4 NIL
+    (x (value (BasicOperator) WRAPPED . #<vector 09a93bd0>))
+    (y (value (BasicOperator) WRAPPED . #<vector 09a93bb4>))
+    (% (value (Matrix (Polynomial (Integer))) WRAPPED . #<vector 0982e0e0>))
+    )
+   ...
+   )
+\end{verbatim}
 
+We also need to check for input error in which case the \$internalHistoryTable
+is not changed and the type retrieved would be that for the last correct
+input.

---  The last history entry is the first item in the $internalHistoryTable 
---  list so car(_$internalHistoryTable$Lisp) selects it.  Here's an example:
---  (3 (x+y)**3 (% (value (Polynomial (Integer)) 
---  WRAPPED 1 y (3 0 . 1) (2 1 x (1 0 . 3)) (1 1 x (2 0 . 3))

---  This corresponds to the input "(x+y)**3" being issued as the third 
---  command after starting axiom.  
--- The following line selects the type information.
