[antlr-interest] Tom, a question

[Bryan S Follins]

Tom,

 

How can I add a rule to the code below which would allow me to enter a
number (like a zip code?)

 

I can already enter letters.

 

OK...The following is ANTLR Code

 

grammar T;

 

r     :     'call' ID ';'     {System.out.println("invoke "+$ID.text);};

ID    :     'a'..'z'+;

WS    :     (' ' | '\n' | '\r')+ {$channel=HIDDEN;};
