What I meant is simple tree parsers which are able to recognize when traversing the tree downwards or upwards, based on special tokens DOWN and UP. The examples present both on the website and in "Definite ANTLR Reference" (the DefRef.g grammar) shows only the Java parsers with the downup() function. It seems however that this function is not present in the generated C source of the parser.
