Hi,

I'm playing with ANTLRWorks 1.2.1. When I try to debug my grammar, the result is a compile error, unreachable statement. Any hints on how to correct this?

Please find the grammar and the console error message included at the bottom.


Thanks,
  András

--- unreachable.g --------------------
grammar unreachable;

ID  :   ('a'..'z'|'A'..'Z')+ ;
DEFINES : '::=' ;
WS  :   (' '|'\t')+ {skip();} ;

prog:   stat+ ;
                
stat:   assignment;

assignment    :    leftValue WS* DEFINES WS* rightValue {System.out.println($leftValue.value + "=" + $rightValue.value);};

leftValue returns [String value]:    ID {return $ID.text;};
rightValue returns [String value]:    ID {return $ID.text;}| sequence {return $sequence.value;};

sequence returns [String value]:    'SEQUENCE' WS* '{' WS* e=rightValue {$value=$e.value;} (WS* ',' WS* e=rightValue {$value += $e.value;})* WS* '}' {return $value;};
