[antlr-interest] passing parameters...

In my tree grammar, I have rules as follows:
statement
: ifStatement | statementBlock[true]
;
statementBlock[boolean result]
: assignment[$result] | compoundStatement[$result]
;
compoundStatement[boolean result]
: ({$result}?=> ^(BLOCK statement*) )
;
assignment[boolean result]
: ({$result}?=> ^(EVAL statementExpression) )
;
In the generated java class, I see code generated in the statement() method
as follows: ( and is not compiling )
..
else if ( (LA2_0==BLOCK||LA2_0==EVAL) && ((result))) {
alt2=2;
}
..
Where did the "result" variable come into the statement() method ? I am
confused on whether I am not passing the params correctly ( although I saw a
similar example in antlr book for passing parameters ).
Thanks
