Hi,

I'm a computer science major graduate student. I'm working on a project
to write a customized version of yacc. Now I already can construct the
parsing machine from any given grammar. I'm at the last stage to
generate a y.tab.c file by incoporating the grammar's parsing machine
into y.tab.c tables yyexca, yyact, yypact, yypgo, yyr1, yyr2, yychk,
yydef.

I was able to figure out how to construct some of these tables by
reading y.tab.c generated by yacc. But I'm still confused about how to
get some other tables like yyexca, yyact, yypact, yypgo.

Can anyone please give me some hint, or tell me what webpage or book I
can get help from?

Thanks a lot!

Puzzled, Tom
