    My now mantra is :
    WwW is doing what BillGates was never able to do - - drag me out of CoSy .
    I continue to be alone in virtually all business meetings I attend in actually using my notebook to take notes . The core of it`s continual utility is its open linguistic foundation .
    For current work towards a truly commercial 4th.CoSy , go directly to : CoSy/CoSy

    HUEMAN : For nons , just noet mie eforts toward universal fonetik speling ( tending toward Italian - Eestern Uroepyan noetaeshon ) .

    MACHINE : Certain computer languages are radically more powerful than the common ones used by the masses of programmers .
    I have been living in and co-evolving my CoSy NoteComputer based in one of these , APL , since 1984 . Some of the algorithms date back to the mid `70s when I learned A_Programming_Language to help understand the matrix algebra foundational to my pursuit of an understanding of psykofiziks .

    The CoSy/APL NoteComputer Environment has incorporated !/Job/Language/HyperText linking , like the web`s , as a natural thing to do since I moved to PCs in `84 , before I was aware of the term .

    Mike Montalbano's PERSONAL HISTORY OF APL


    Always Remembering Ken Iverson , father of APL
    The main English language publication about APL these days is Vector.org.UK .

    I think the best downloadable trial APL is at : IBM APL2

    The best commercial APL is Dyalog .

    A somewhat less expensive APL is MicroAPL

    Arthur Whitney's APL derivatives at Kx.com are world competitive large scale time series analytical database systems . It will be a while before I will be migrating my accounting from K.CoSy .

    SmartArrays by my friend Jim Brown , who was the chief architect of IBM's APL2 , and James Wheeler who wrote what is now APL2000 , now APLnext , I believe will give K a run for the money in many large scale applications , especially non time-series . E.g.: : DoD inventory systems .

    Ken Iverson's very abstract and mathematically oriented final notation is J developed with Roger Hui .

      • http://www.kx.com/ ArthurWhitney `s language : K , which I consider to be the most conceptually advanced language in its abstraction of the essential structures of data and algorithms . The size of his fully working demo executable is just 128KB .
        His syntax , tho , has a number of idiosyncracies and , most egregiously does not allow creation of infix functions . Instead multiple arguments must be listed in ' [ ; ; ; ] ' list notation .
        Thus | ( A f B ) g C h D | becomes | g[ f[ A ; B ] ; h[ C ; D ] ] | ( corrected 20070604 . was : | g [ f [ A ; B ] ; h [ C ; D ] ] | ) .

         the benchmark is loops, text-processing and stdio.
                  we do vectors, data-processing and mmap. 
      • Older view : \COSY\COSY!/Job/ArthurWhitney`s:K An e-mail I picked up from comp.lang.apl archives .
          ( 960722 | Incidentally , I stayed in NYC THU.JUN,960620 to see Arthur give a demo of K at UBS . In a demonstration of disorganization unconscionable for a bank with global pretensions , the projector for the Sun hi-res monitor could not be found . Perhaps 2 out of the much - beyond - the - ordinary SigAPL crowd could see any of Arthur`s actual conversation with his machine . It makes it not worth my uploading my notes .
          To understand the value of this region of ComputerLinguistic space , note that UBS is the only user of ( and , in fact , thru `97 06 , has proprietary control of ) " K " . Apparently 4 individuals , most or all ex- MorganStanley , support K full time .
          Conclusion : UBS spends around %2 M $ on the language each year . )

    FORTH , the minimal extensible language is the one language I`ve met since learning APL with substantial ' philosophical ' import .

      The algorithm , while much more illuminating than "Hello World" , is still far too simple to differentiate deeper structural aspects of the languages ( altho many of the examples display the overhead required for those structures ) .
      Many other examples , perhaps out of boredom , elaborate or obfuscate the basic problem rendering them incommensurable . The APL2 example , for example , essentially creates all verses in parallel , and thus is a good example of APL's intrinsic parallelism , but is not the sequential algo intended .
      The K example is such a fugue I think it must have been written by Steve Apter .
