Memory is coming back. It's either in the Dragon book, or in one of the more formal books by Hopcroft et al. Symbols don't get pushed back onto the input stream. It is the stack which may contain terminals and non-terminals. In one of the strategies, the initial state of the stack is the input stream. I apologize, but I won't have time to research the references until next weekend, or later. For now I'm just happy sharing that the approach I knew would work, did work. Cheers! -- Juancarlo *Añez*
