Hi people,

            Can anybody help me with this: Whenever there is an unknown
token, parser throws RecognitionException. Can I, somehow, extract this
token that has caused the exception. E.g I have a construct say:



If ( a> 10 ) then

            Print(a);

Endif;



Someone makes the following error:



Ifddd ( a> 10 ) then

            Print(a);

Endif;



Now "ifddd" is syntax error and this is an unknown token. Can I extract
this in RecognitionException catch block by some method??



Please help.



Abhijit.
