[antlr-interest] Token Mismatch

[Brisard, Fred D]

I'm sure this is a novice question but I can't seem to find an answer
that I feel comfortable with.

It seems like any literal specified in the parser rules becomes an
implied token.

Using the basic example T.g -

grammar T;
/** Match things like "call foo;" */
r : 'call' ID ';' {System.out.println("invoke "+$ID.text);} ;
ID: 'a'..'z'+ ;
WS: (' '|'\n'|'\r')+ {$channel=HIDDEN;} ;

I get a MismatchedTokenException I run this in the ANTLRWorks debugger
for the input

call call;

I would like the second call to be identified as a token of type ID.

Any help is appreciated
