Got it, thanks again! But I've got another doubt, what's the difference between ival&i_tkval, pval&p_tkval in YYSTYPE? updateI've just checked other symbols like GRAMBLOCK, it should be parsed by Perl_parse_block in toke.c, which is called as parse_block , but the strange thing is : they're never ever called from anywhere. so when will yyparse got token GRAMBLOCK from yylex ?
