Personally, the page I always refer to for J parsing issues is http://www.jsoftware.com/help/dictionary/dicte.htm but any page on jsoftware.com that mentions bident is likely to cover the topic. > I am still a bit puzzled by references elsewhere in the documentation > (J5.01 Non-Compatible Changes) to various classes of tridents and bidents > no longer working with J 5.01.

For example: +/ ( . . . ) * Here, . . . would be an example of a trident which is composed of conjunctions. (This example expression has no practical use that I am aware of.) This was removed, I think, because it mostly confused people and because explicit definitions can be used to do the same thing with arguably greater clarity. +/ 2 :'(u . v) . (u . v)' * -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
