It would be better to say "the same as" or "identical to" rather than "similar to", because any deviations are unintentional (i.e., bugs). > +In a deferred semantic action, its effect is currently not well tested. > [EMAIL PROTECTED] The effect is probably a syntax error at the split point. > + Let's say instead In a deferred semantic action, its effect is undefined. > +Note that it is also possible to access the semantic value of the look-ahead > +token, if any, from a semantic action. > +This semantic value is stored in @code{yylval}. OK, call me picky, but I *REALLY* dislike the phrase "note that", and would prefer Within a semantic action, the semantic value of the look-ahead token, if any, is available in @code{yylval}. > +Note that it is also possible to access the location of the look-ahead > token, > +if any, from a semantic action. > +This location is stored in @code{yylloc}. Likewise, Within a semantic action, the location of the look-ahead token, if any, is available in @code{yylloc}. _______________________________________________ Help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
