[antlr-interest] how to make different variable and others

[Peizhao]

Hi,

I have a file which will contain the followings:

ABSTRACT a short description about what this document is about
ABSTRACT this description is not output to users.

these ABSTRACT statements are conflicting with my variable name
definition. 


ABSTRACT_DESC	: "ABSTRACT " ANYSTRING;
VARIABLE_NAME	:	('a'..'z'|'A'..'Z') ('a'..'z'|'A'..'Z'|'0'..'9'|
SPECIALCHAR)* ;

therefore, my question is that how can i make them different.
