[antlr-interest] Rule question.

[Gevik babakhani]

Folks, 

 

I have a question regarding Parser rules.

Let's say, I have the following rules in my lexer.

 

A : 'a';

B : 'b';

C ; 'c';

 

These three rules are all mandatory and must be present in the source file.
BUT the order of appearance in the source file is of no importance. One
could enter abc or cba or bca, cab in the source file.

How do I describe that in my parser rules?

 

Thank you.
