[antlr-interest] How to deal with subset characters for lette r-Thanks in advance

[mzukowski at yci.com]

E, S and L need to be keywords, not separate lexer rules.

Hi,
I have been trying to use the following grammar rule:
marker: E | S | L;

Then, in the lexer, I have two rules:
LETTER: (a..z| A.. Z);
E: 'e';
S: 's';
L: 'l';

But the antlr give the nondeterminism error for that. Does anyone 
have some ideas for it? Thanks in advance.

Yu-
