Hi.I  am writing a program with lex and yacc. In lex I have two chars that I want to pass to yacc at the same time. However, because yylval is a union that is  impossible. However, I have read that one can use structs. How do you do this?I need some code. Thanks.

if you have your union which currently contains something like char text[100], why don't you change the char text into a struct, like

%union {
struct {
char first;
char second;
} bi

and refer the vars like yylval.bi.first
}
