Hello Fellow MIPSers,

  Has anyone else out there had opportunity to write a compiler
  using the MIPS version of YACC(1)???  I for one, would just like to
  say "bravo!" to the person(s) at MIPS responsible for generating this
  version!  It performs better (ie. faster and has better error recovey)
  and has a wonderful debug mode (kicking out not only, "shift" and "reduce"
  conditions, but the productions in use also!)

  Well now the (not so) down side... does anyone know what a configuration
  in a state of the form :

  expression : expression PLUSOP $$56 error

  means?  (I don't know what "$$56" is supposed to do for me, and it's
  not in the documentation -- at least I can't find it.)

  Many Thanks!

Cliff
