[antlr-interest]Skipping a Lexer Rule

[Nijesh Panchratna, Noida]

Hi !!
My rule in lexer -
ROLE
:("$Role")+
 (' '|'\t'|'\n' {count++; newline();}|'\r')+
{$setType(Token.SKIP);}
;
ignores $Role in a file and doesn't pass it to parser.but it seems it does
pass something else.
Also, I am not clear what happens if my file doesn't contain this $Role word
i.e I want this rule to execute if there is a $Role word in the file else
skip this rule.How can I achieve this??
thanks in advance.
Rg
