Taking tacit expression as a pure-functional portion of the J language, how can this solution be effected? For some weeks I've been trying, unsuccessfully, to envision J equivalents to Haskell's monads and arrows. It may be that because J is a multi-paradigm language there is no possibility of a parallel, but I don't find that idea plausible. The limited functional purity of J may make such solutions unattractive or awkward, but since there is a rather clear-cut range within which functional purity is maintained, my guess is that the technique you applaud can be accomplished in J. -- Tracy ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
