But you can have naturally occurring arrays which would be recognized as sets when that was not the intention. Examples include: '123' -.L:0;:":i.10 i.&.>#:2 And, this does not solve the related problem of using the wrong set. Personally, I think correctness is best dealt with using testing. If the result is not correct, the code is wrong. If the code is wrong and the result is correct you need additional tests. (But good modularity demands that the tests be factored out of the production code.) (Though, granted, you can find advocates opposed to modular design.) -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
