Keeping data in structure with ; is a great thing. However I do not understand the logic to get value error:
value=: 123 novalue |value error: novalue (1 2 3);'abc';value;novalue 1 2 3 ; 'abc' ; 123 ; novalue NB. No value error with novalue (1 2 3);'abc';novalue;value |value error: novalue NB. Now J gives value error with novalue | (1 2 3);'abc'; novalue;value Is there any method to always observe that novalue is not defined?
