    / 20060120 / I have unprotected the member area so if you want to explore K.CoSy ,
    which remains the only interactive development environment for K , be my guest .

    Current Focus : CoSy/CoSy

    K Scripts & Tools

    • .CoSy : Verbs and their help and definitions << ESSENTIALLY ALL OF K.CoSy <<

    • Arthur's Kriptic Kdoc Arthur Whitney's console documentation for the 2002 version of K  K.CoSy is written in , perhaps the only APL style workspace IDE ever written in K itself .

    • .CoSy.Fact : dictionary of basic math and physics constants and English to metric conversion factors .

    • Basic Search Functions

    Arthur Whitney's K is by many measures one of the most powerful programming languages .
    K.CoSy turns it into an interactive "NoteComputing" environment .

    CoSy "Turn on and Use" Note-Computing Environments Customized with K.CoSy.Kdb supply Individuals and Groups who earn their living thru analytical thought with the most powerful tool for realizing those thoughts on data of any scale .

    Already using Kdb ?
    You've got to see the immediacy and flexibility of CoSy as your IDE and interface for your most sophisticated End Users . get info

    " So well done, CoSy has stimulated me into trying to learn K "

    Old flat APL CoSy ( blue )
    in front of neonatal K.CoSy
    After 17 years living in my CoSy "notecomputing" environment created in STSC's flat APL+PC , I have since Thanksgiving 2000 created a similar working and programming environment in Arthur Whitney's K language and its tightly coupled GUI . ( See )

    Already K.CoSy provides an extremely productive workspace like environment previously impossible in K which is itself one of the most expressive and perhaps the fastest language yet created .

    Among my uses of K.CoSy is the preprocessing of these web pages with a small vocabulary I have constructed to allow embedding of arbitrary K expressions in my HTML . ( View the source of this page for a couple of examples of embedded K . )

    If you have an interest in exploring K , K.CoSy's open definitions , interactivity , and memory of every thing you do , greatly ease the task . The only silver lining to the horrendous disk crash I suffered mid June is that reconstructing from scratch , the code is much cleaner and more mature .

    Caution : K and K.CoSy must be considered eXtreme programming environments .
    If that appeals to you , prepare to be amazed . If not , K and K.CoSy may be totally inscrutable to you .

    ( move cursor on pik to see title comment )

    Here is what you see when you click "click to start" opening K.CoSy .

    Click .CoSy.text to see the whole contents of the variable `text when you first load the current version K.CoSy .

    These should give you a flavor of the open nature of K.CoSy and a glimpse of its broad utility .

    Klik to see Help on the defined Keys in `text .


    K.CoSy , being young and developing open code , lends itself to offer by subscription . SORRY , charter subscriptions have done their job and are a thing of the past . Please contact us directly about integrating CoSy into your business life .

    Charter subscriptions are available for just $30 . Subscription includes access for one year to the source files in the protected MEMBERS directory and the ability to post to the group ( and , of course , to ask me any usage and technical questions . . Current members of the CoSy/Notecomputing group are automatically Charter Subscribers with full access privileges .

    To become a member of CoSy and experience its extreme simplicity :
    1. Go to and download a copy of K ( or Kdb which includes K ) . Download their docs too ; CoSy assumes you know or want to learn K . CoSy does a lot to tame K , but you will see what a wild mindmeld Arthur has condensed .

    2. Subscribe to K.CoSy NoteComputing Language Pool .

      Drop me an email or give me a call letting me know you are writing a check .

    3. I will then add you to our members' mail group , and email you the information to access our members' directories and files including how to download and setup K.CoSy .
    This is all very fresh , please contact me with any questions or suggestions .
