Lev and dex are in an older version of J. Is it possible for you to use the older version of J for your class? They were removed a while back. I never understood just why. I assume that the costs to support outweighed their benefits.
As far as writing programs using the explicit adverb and conjunction definitions for lev and dex is just fine, but it is not pretty. Lev and dex allowed for tacit definitions for many adverb conjunctions which, to me, should be an integral part of tacit definitions. Could they have been removed so that they could be used for some other definitions some time in the future? I still miss them. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
