Following are the changes made in the 9/99 reprint:


(xix) 3rd paragraph

   "Appendix C, Berkeley Yacc, ...widely used free version of 9781565920002 ..."

   "9781565920002" now reads "yacc"

(46) The 6th paragraph read:

   "Similarly, this next expression matches the FIRST but not the
    SECOND:

FIRST

with

        action { execute | menu | quit | ignore } [<name>]

             |   b Z


(227) In the second to last paragraph the last sentence read:

        ...so x2 which uses z2 is part of shift conflict and x3 is not.

	...so x2 which uses z1 is part of shift conflict and x3 is not.
