PROJECT ASSIGNMENT #2
                                    ---------------------

                                Due Monday, February 14, 2005


        1.   Modify your lexical analyzer to return  tokens  to  a  calling  procedure
             instead  of printing the token code. (The source program should be echoed
             as it is input.)

        2.   Design a parser for the Two-Level Grammar syntax which calls your lexical
             analyzer.  You  may  use  any  parsing  method  that  you wish, but it is
             recommended that you  accomplish  your  parser  by  rewriting  the  given
             extended  BNF grammar into a form suitable for input to Java CUP and then
             use CUP to automatically generate an  LALR(1)  parser.  If  an  error  is
             detected, it is sufficient to print an error message and halt processing.
             Use the test programs you have been given to validate your parser.
