J has some operations which are notationally convenient but which technically are not needed. For example -. could be replaced by 1- However: > 2) How would the expressiveness in J and K compare? K is more expressive in the context of relational tables (for example), where J is more expressive in the context of higher ranked arrays (for example). [This just scratches the surface of their differences and is not meant to be an adequate comparison of the languages.] > 3) Is it that K needs less because the usage scope is well defined? I believe yes, at least in part. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
