This looks like a Flex question:

It looks as though you want to write some debugging code. Flex returns a
pointer to the lexed text in yytext, temporarily \0 terminates it until the
next scan, giving the length in yyleng. Have you tried:
[A-Za-z_][A-Za-z0-9_]* {
   printf("\t\t<sdftext inside FLEX is %s >\n", yytext);
                          return NAME; }

If you want to put the string into Bison's yytype, use a const char* and
make sure to duplicate the string before returning from the lexer. Then you
have to figure out how to cleanup those dynamically allocated strings. --
Therefore, I use C++, which can do that cleanup automatically.
