[Flex-help] Starter question.

[<Wor...@gm...>]

Hi everyone, i've got me the book flex&bison and have troubles with one 
of the first examples:


%{

#include <stdio.h>

%}

%%

[_a-zA-Z0-9]+\(     { printf("This is a function name %s (steps=%i)", 
yytext, steps++); }
.|\n                    { printf("do nothing"); }

%%

int main(int argc, char **argv)
{

     yylex();

     return(0);

}

Now my problem is that also strings like 12342welcome( are beeing 
"marked" as beeing functions ... what am i doing wrong here ? the 
default route .|\n is said to do nothing, so why does he matches also 
digits with my function catching example ?


best regards!
