Sorry to be a little slow in posting this , but , hey , the disk crashed .

  This is the first newsletter composed in  K.CoSy itself . Its utility , and my
  comfort with it , has evolved that far . And this letter contains several
executed
  examples which are simplest to work thru live in  K.CoSy .

  Everyone in the NYC area , remember  the CoSy_MidWinter_Gathering 15
  ( 0 origin ) is coming up Monday Feb 4 . See
   http://cosy.com/current.htm#20020204 for details .

  I expect to get out the second part of  "Y K ?"  by the end of next month .
  It will discuss the flexibility provided by K's syntax to "factor" problems
along
  the most useful lines .

.R />/ `.CoSy
/(/ 1043 / Astoundingly , Friday 020104 , I had another destructive disk
  failure on the Sony R505TE I bought July 24 to replace the Z505SX whose
  disk failed in June . Pulling apart the -SX to get at the ( Toshiba ) disk
  to FedEx it off to Carbondale IL to be retrieved , I broke the clip on the
  connector to the touchpad . This error defeated reassembling it with the
  IBM 20G drive I dropped near $200 to pointlessly get quick .

  I am now up on the Z505SX which Raj Chetiar's brother Vishu just
  reassembled and reloaded with Windows 2000 .  Vish had the brilliance
  to simply plug in a mouse to obviate the touchpad problem .
  This is the first time I have ever used a mouse for more than 5 minutes .
  It's an interesting experience , but I continue to prefer the old EMACS
  aesthetic of never having to move my hands from the keyboard .

This time I just lost material since 011211 , and most of that time I was
accompanying my brother Jack , http://cosy.com/art/jacka/jacka.htm , out
to our sister Joyce and her girls and parrots and big white dogs and horse
out in Colorado Springs . In 28 years , the apron of the Front Range has
has been infected with a continuous rash of human habitation for at least
the 160 kilometers between CS and Boulder where I visited my high school
( http://Culver.org ) adventure bud Gary Neptune
( http://NeptuneMountaineering.com ) and his wife Bibi who met each other
at Everest base camp .


Anyway , I've reconstructed a couple of the few words I defined during the
lost period , and I think they are interesting enough to post .
In any case , that absolutely backs them up .

Work in K.CoSy follows the hierarchical dictionary ~ directory , structure
of the K-tree .  For instance ,I have my personal work and accounts in a
Job dictionary named  `BobA , and work on Raj and my partnership ,
CoSy_Homes , is in a Job dictionary , `Homes .
So it's very common to be writing and executing , e.g. :

`show $ `BobA

. It's so common that I keep lists of lines to " `show $ " this or that
around in the various Jobs I work in . It's so common that I keep lists
of the most common objects , for instance `.CoSy.BobA.Ref , in which I
keep all my account numbers and passwords , etc ,  in the  f8 Command
window , `.Cmds .

But , one of the aspects of  K.CoSy  is keeping logs of daily activity ,
For instance , here are my notes in  `.CoSy.Boba earlier this morning :

/ 0844 / email  / 0936 / Emilio m w Andrea , cb ~ 12 / c> / Raj

.  I wanted to be able to display the job containing all my interactions
with  Raj  with just a keystroke . And I wanted to be able to do it on
names appended to earlier work . Therefore , I created the words below ,
and modified a couple . I've found this mechanism so time saving that
after downloading my last backup of my working  c:/CoSy.csd  from my
web host , I reconstructed the vocabulary so I could start  `BobA
without writing even one redundant  " `show $ "  .

Here is the vocabulary : ( All of this is executed in the Root : .CoSy ) /)/

text..f9..h : " `show $ `\" name after last comment token in current line\" "
text..f9 : " `show $ . ( .R `lastseg ) _v . _i "

lastseg : { *| tokcut[ C ] C , x }
lastseg..h : " returns section of string after last comment token "

C : " / "  ;  C..h : " the primary comment symbol "

/  `tokcut  is previously defined
tokcut..h
" split string `y at multi char token `x "

/ I also needed to regularize my timestamps to be compatible :

hm : { C , ( -4 # "00" , $ *| ts x ) , C }
hm..h
"current time . hour & minute"

/(/  That's it .  It reduces showing an object to writing down its name , eg :

`.CoSy.People.Raj

and tapping f9 . ( Incidentally , I tried  f10 , but that seems to be hard
wired to be an alternative "alt" key . )
( Note in the example from my notes above , I have a variable `Raj defined in
`BobA holding  `.CoSy.People.Raj . )

Here are a couple of other recent miscellaneous new words :
/)/

KtoM : 1.609344  ;  KtoM..h : " Kilometers % Mile "

matchR : { ( .:' x ) ~' .R x }
matchR..h :  " do objects in active dictionary match same objects in Root ? "

( .R `matchR ) `text. `r.    / Its motivating use .

/ 1311 /

A final thought :  Sasha Skomorokov pointed out ( in APL ) that

1 ~ { x ~ | x : 10 _vs x } 2002

which was last true in  1991  and will not be true again for  110  years .

may this symmetry presage a peaceful and productive year .

CoSy-NoteComputing Newsletter @ 0112  /               Y K ?   0 : STRUCTURE

  Why have I moved from ancient flat APL , skipping the great modern nested APLs
,
  all the way to the youngest , most independently minded evolute of this
language
  family ? What are differences , the pros and cons of K versus other APLs and
Ken
  Iverson's own evolute J ?

  The first part of the answer , a discussion of and introduction to the
structure
  of  K , is now available at  http://cosy.com/K/CoSy/Y_K.htm .
  A number of screens images of  K.CoSy  illuminate the concepts presented .


  I have now been working with  Kdb  co-resident with  K.CoSy  .  No problems .
  Having Kdb ambient , I can look at its 671 objects with 595 unique names
  " from the side " , if you if you will , and hope to avoid a lot of redundant
  work , and maximize compatibility . For instance , I have started using
  Kdb's  .d.ds  and  .d.sd  to convert timestamps to and from Kdb's format .
  ( Kdb's time handling functions are what I most covet . I know there's a lot
   of brilliant experience there . )

  So far , I have worked thru sequences to export dictionaries from  K.CoSy
  in the form of  .kdb  database files , and vise versa .
  I have been reminded of the virtues and limitations of the relational model ,
  ordered or not , which I have not dealt with since rewriting Xerox's WW
  forecasting system when I first came east back in 1980 .
  While it provides a useful discipline , it far more limited than  K's  natural
  hierarchical structure , made ambient by  K.CoSy .


  Life is getting more back to normal here at Peck Slip , tho I'm worried
  Con Ed may have designs on the wall holding their Haas tromp l'oeil mural of
  the Brooklyn Bridge which has graced my view all these years . I've uploaded
  a picture of what's happening to   http://cosy.com/home.htm .


  Til next time ,  Hoping happy holidays  for all .

Dear group ,

  Jeez , what a semester .  First the disk crash before
  APL2001 in June ( http://cosy.com/cal01/DiskCrash.htm ) ,
  then 0911 ( http://cosy.com/y01/d0911.htm ) .

  But , as soon as the Fish Market ( back for its 2nd week )
  cleared out abnormally early this morning , Con Ed across
  Peck Slip resumed back-hoeing the Belgium Blocks and cutting
  up the concrete on the Slip and South St , and brought in
  incredible cranes to install new transformers , and their
  radiators , to further re-empower Downtown Manhattan .
  ( I've taken clips . )


  I , myself , have just uploaded the second edition of  K.CoSy
  which continues becoming an ever more powerful tool to keep
  up with the business of everyday life around here .

  I call it a second edition rather than just an update because
  some changes are pervasive , so that it is best to simply
  start it up , then copy forward any words you have created or
  changed since the 0th edition .

  The most consequential changes :

   ~ Changed tag for Root dictionary from  `.D  to  `.R  for
     coexistence with  Kdb  ( which uses `.d and `.D ) .

   + In  `text  , `f6  executes in local dictionary ,
      `f7  executes in  `.R  .

   + Starts up with Console "\" help screens displayed in  `.r .

   + 27 net new words bringing the total , all documented ,
     vocabulary up to 165 :
        `Comments `DSORT `Dat `Dxeq `FNSCON `Jobtext `PRTBL
        `Pallet `S `UD `allmatch `brak `c2f `d2h `dcat `dic2ltab
        `dics `dospath `drpl `dsel `emptyd `fac `i `leaf `linv
        `n `nuld `nuldic `signum `sortdic `t2d `t2h `tab2dic
        `tab2html `to `v `viewhelp

     `f2 displays them with their help .

    + Al la comments of  Dennis Shasha , all sloppy references to
      "directory"s when I meant K "dictionary"s have been corrected .


  Over the next several months , I expect to be posting notes and
  scripts to do a variety of the activities , from hierarchical
  ledgers to HTML publishing and table i/o this vocabulary
  facilitates .
  Note that in K.CoSy , a script is not just something you can
  load from a file , but a set of lines that can be kept around
  in `text and executed in or out of sequence , edited ,
  copied , etc , as needed .

  Please let me know if there are any particular tasks you would
  like discussed .

   Dear PinkLady ,

   K.CoSy  is one of the world's most powerful interactive
   programming language environments .

   Being open code , like a book in a bookstore , I must
   require an up front subscription fee .

   But , at $30 ( student discount available ) , it is the
   match of many $1000+  packages .

   Is this what you thought you were signing up for ?
   If so ,  fabulous !  Be ready to have your head stretched .

   If not , may your path also be fruitful .

  Monday 12:45 Con Ed got power back here at 42 Peck Slip
   with cable that evening .
  Tuesday did laundry , chatted with Richard McGorty as he
   delivered our backed up mail .
  Wednesday morning my computer phone line line was live
   but connection uselessly unreliable until evening when I
   scanned my accumulated 250 non-news e-mails .

   I planned to get to get this out first thing
  Thursday morning but in my snmail was an invitation to
   Bob Flaherty's  http://www.EquitiesMagazine.com
    Small Cap morning at the Grand Hyatt .
   I had to go particularly because for the first time in years
    I'm armed with 2500 real business cards ( The image of the
     http://CoSy.com  cover page ) included in a run by my
    friend Frank Black of  http://PostCard500.com  a couple of
    weeks ago .
  When the express came into City Hall station , full --
   as usual ; I may have actually  sighed with relief .
  When the luncheon ended up full , with some very pertinent
   and interesting companies ( see my notes at
    http://cosy.com/current.htm#ThisWeek . The presentations
    are available at the Equities website )
   the return to normalcy was palpably reassuring .

/2019/ I'll finish this ( and deal with my accounts )
   in the morning I'm because in my mail is an interesting
  invite to  The Time is Always Now  at 476 Broome .

  It looks to me that New York is back to work
   with a vengeance .

The real heart is that if you tap `f6 when in `text , CoSy executes
the line you are on in  K  and assigns any result to  `r  .

Everything else has just been built by writing and `f6ing and
and rewriting and ref6ing lines til they do what I think I want  .

Great .  Now you can work down thru those examples in `text .
You will find a simple example of editing a multi-line fn just
by formatting and displaying it in `.r and editing it there .

.r : VM @ $ f        / Display the function  `save  in  `r . edit it .
f : . MV .r         / after editing , redefine .

Woops ,  I generalized  `MV  to work with delimiters other than
newline "\n" .

  Needs to be
f : . MV[ "\n" ] .r         / after editing , redefine .
  or
f : . MVn .r                / after editing , redefine .

Yea , best to have the PDF K Reference Manual available to decipher
the sentences making up CoSy .

If you look at the boot script , /CoSy/kboot.k  ( execute :
0:         "/CoSy/kboot.k"  / )
You see the \m settings of the font . You can try to improve on
my settings .
( The example of reading and editing the boot script is in the initial
.CoSy.text , but I see it says  "/CoSy/kboot.txt" instead of
"/CoSy/kboot.k" . It will be fixed in the next release , mid September . )

When you have entered a line for editing , the cursor does become a nearly
unnoticeable skinny vertical line . Often to find it , I up-arrow or
down-arrow to highlight a neighboring line to find where I was .

Arthur has said that he has not worked on the GUI since `95 . Perhaps
with more use , there will be motivation to revisit this aspect of K .

CoSy.csd is a K data file , not even close to text .
In the examples in `text , is :

.r : ( Q ; ( ~ Q ) @\: `h ; .:' Q : sort fns _d )    / fns w help if any .

which will display a table of all the functions with help and definitions .
You can hit Alt PrintScreen to capture it as an image .
I need to make a simple table to text converter so such things can be
output to -.txt files easily .

>3)
>Are there some K scripts that can be read? Scripts containing functions
>and scripts containing applications.?

Start by executing , `f6ing , each of the example lines in the `text
window .

I've just added the following as the first example to execute

1 - 2        / Tap the f6 key to execute this line . note what happened
             / to `l and `r .
             / Tap  f5 . See it inserts  r  in the text .

If you mean by applications things like ledgers an mail-lists , basic
templates or prototypes are included as objects in .CoSy .
No script has ever existed to create them .  See down toward
the end of the examples . Generally you can just  f6  the names
of any items to see their innards .

>Regards

Thanks for the great feedback .  It is only with it that I can know
the edges which most need sanding and polishing .

No problem .

>(i)        Does K.CoSy provide an IDE (integrated development environment)
>for K or equivalently is K.CoSy just an IDE for K?

I don't quite understand the criterion for that term .  I think the
answer is yes . If you are familiar with traditional APL workspaces
and session managers , its like that .
If you click on the screen image to see it full size ,
  http://cosy.com/KoSy/KCoSyscr.gif , ( which actually is from before
  the disk crash ) and look at the highlighted window K.CoSy.acnts.BobA ,
you will see the the highlighted line in the big window `Current ( which
I now call `text )
   1 - 2
I had pressed the f6 key to execute the line so you see it displayed
in the window  `l  and the result displayed in the variable  `r .

The immediacy of these simple mechanisms to facilitate hacking til
you get it right is enormously greater that recompiling whole
scripts .

>(ii)        If it is more than an IDE, what would its main uses be?

If it were not for the lack of knowledge of cursor location within
lines , I would even be doing all my text editing in it .
But , beyond being a super calculator , I've so far created simple
"prototypes" for not only new "Jobs" like  `.CoSy.acnts.BobA , but
also simple ledgers and lists like those shown .
Yesterday I had to work thru the conversion of Schwab account
histories cut and pasted from their screen into a simple ledger .
I encapsulated about 3 new functions to do things like removing
leading blank columns , evaluating numbers with embedded commas
and dollar signs , etc . These will be in next month's udate .

I think you have the gist of it .

Hope this answers your questions . Please let me know if you
need some further info .

  This must have something to do with the merging of eGroups groups

  K now loads itself into c:\windows\ and runs from there .

  By "root" , I mean c:\ . so the name of the "workspace" directory
  you start in  ".CoSy"  in  K  simply maps to the dos directory
  name  \CoSy  . ( Note , inside K you can simply use the UNIX/WEB
   forward slash : "/CoSy"  which is easier because  \  is the
   escape character in K so you have to write "\\CoSy" in K . )

  Thus any subdirectories you might make , like  .CoSy.BobA  or
  .CoSy.Acnts  will map to MS  \CoSy\BobA  or \CoSy\Acnts .
  Note also that while  Arthur has implemented the enormous
  convenience of automatically creating on the fly any directory
  path you assign to , eg :
    .CoSy.People.Raj : newjob ; .CoSy.People.Raj. : newjob.
  works even if People never existed before . That's not true ,
  of course , for writing to MS directories .
  That's why I suggest making a directory  \CoSy right from the
  start .

  Thank you .
  We'll get this solved . Worst happens , I'll email the files .

Hi..
My original reply had the wrong return address on it - but Yahoo sent me
a new authorisation code, anyway.
I am now registered in Yahoo/group with the name of dalis_basel
The name dalis was already taken.

When I use:
http://groups.yahoo.com/group/cosy-notecomputing/files/CoSy.csd
I am told, unsurprisingly, that dalis_basel is not a member..
Please advise.

Also, I am on Windows95 - what do you mean by downloading

I'm guessing that this means:
c:\windows\

Is that right?

Thanks in advance.

Friday , I started a response to the several comments on my
  previous post . I ended the weekend with the few lines of  K
  below , which , lines of K being worth lots of lines of other
  things , will provide context .  Since it`s sort of a kernel
  abstracting the essential extensibility-from-within that is
  what has made CoSy survive up to now , I`ve called it that .


.CoSy.Current  : , " Current ,: , \"  \" "
.CoSy.Current..kr : " r : . * _v _i "
.CoSy..c : `form ; `show $/: `.CoSy `.CoSy.r ;


  It Displays the line |k|    Current ,: , "  "    /k| , which , if
  you right click it , creates a new line in the display .
   ( Thanks Andrei , for mentioning .kr . It`s not in my downloaded
    documentation . )

  Move focus to that line , write an executable K expression there ,
  and right click it .  Nothing happens . Move focus off the line ,
  then right click on it again , and the line will be executed and
  any result displayed in  .CoSy.r  .

  Despite the clumsinesses of having to shift focus and resort to
  the mouse any time I want to execute anything , I expect to live
  in this essential edit and execute loop as long as I use K .
  I`m sure I can do quite a lot with the 3 signals available .

  This is the piece of interface that will count to me , and ,
  of course , it`s the basic input widget for K .

  I`ve always felt  K  showed its legacy of presenting masses of
  inputs done by someone else . The input side seems to have an
  air of incompletion about it .  ( The relatively recent
   reification of  .kr  augers the notion . )

  All that`s needed is that  _i  extended to include the cursor
  position within the line of text , and a " .kb " event
  be added with the keyboard index of the event returned
  in , e.g. ,  _kb  .

( `BobA ; "http://CoSy.com" )

  Incidentally Andrei , when I first tried setting up a Keyboard
  execution table , it was on  4MHz 8088 .

  Before the US elections , I was too busy with
   http://cosy.com/views/travlgat.htm  to add my comments on this important
  issue .


  I want fundamental facilities commensurate with the level of abstraction of
  the language itself . I want to build whatever I need from that foundation
  in K itself . We`ll really see how fast K is at the EndUser end .

   At the most coarse , let me have a map from a character array to a fixed
    font window . And , Let me see every keyboard event .
    A standard mapping , in open K , of those events for ordinary text input
    would be a needed exercise .

   Better , give me a map from pixel lists to windows .
    And let me see some  K-meisters  create a little vocabulary to treat it
    as partitioned into sub-rectangles and implement the fixed font level
    above  in open K .

  Then I`d be up to the functionality I just about had back in `84 in
  CoSy in STSC APL+PC before upgrades to Windows eliminated the direct
  screen mapping . ` Never had the performance to interpret all keyboard
  events tho .

  Oh yea , let me know where the "mouse" is and what the buttons are doing
  , too .


  I`d like to know more about the nature of current interface between the
  existing K gui widgets and the K engine .  I remain impressed with with
  Tom Zimmer`s WinFORTH which simply taps into some table of the names of
  all the Windows entry points . You are responsible for learning what
  they all do from MS documentation if you need them .
  Unfortunately Zimmer himself apparently recognizes the excessive
  complexity his code implementing his editing environment within his
  own FORTH upon those bare Win calls . He`s totally stuck in FORTH`s
  low level thinking .

> 1.  What facilities would you want from a dedicated K programming editor?
> 4.  How do you write K programs? (i.e what's the procedure/routine/working
>     style?)

  I continue to use my own CoSy/APL environment I basically wrote years ago
  in open APL as a general purpose note taking and computing interface .
  One of its key aspects is that tapping  F6  sends the line under the
  cursor to the APL interpreter and space is opened in the following text
  for any result generated . There are several variants on this action .

  I`ve constructed a few words to communicate , thru files , with a little
  hosting kernel in K  and have programmed F10 to execute K expressions
  in the same manner as F6 executes in APL .

  Altho the old DOS environment is dead-mouse , the environment has a number
  of facilities , coming from it`s open code nature , I still have not
  seen elsewhere . A basic point is to never have to write anything twice
  and to be able to edit and re-execute any line I want until I get it
  right .

  It is the continual redefinability of its open code that has kept it
  alive .

  Bottom line , I am generally living in an HTML string which may have
  all sorts of other stuff , notes , programming , whatever , in
   < ! - - -  comments  - - > .
  An HTML browser based interface might be a very practical direction
  to go as Jim Brown and James Wheeler have with their  SmartArrays
  Java/C++ function library .

Finally ,  I have never seen what these Emacs based interfaces are
  like . The closest I got to emacs was a thing called
   FINE Is Not Emacs  which U. of Rochester had .
  I would be very interested in seeing one if some one here around NYC
  might be so kind .  Actually , I think it would be interesting if
  some occasional User meetings were held here again . I think there
  is enough evolving info to be exchanged .

  Reminds me of when in 1976 at the Optical SocOfAmer Psychophysics conference ,
  an elder I cited in my paper for having brought ( 1-D ) signal detection
  theory into Psych Dept consciousness  told me that what I had just presented
  couldn`t be done for another generation  -
   -  and damned if they didn`t about succeed .

  I see the great challenge for Libertarians to succeed , is to explain how
  commodities are alocated when there is so much less work " to go around " -
   - when the irrational paperwork backed by Government guns ( to paraphrase
    Greenspan ) is gone .

  These are people`s whole lives we`re talking about .

  Stability comes from living in it ;  most fundamentally having one general

  Doing it over , I`d do it much more cleanly .

  By "too-simple rule" I imagine you mean edge conditions which demand more
  complexity to algorithms than expressing the rule for the entire interior .
  That`s life .

  Back around 1980 Mike Montalbano of IBM when introducing his
   "APL Blossom Time" ( see : http://cosy.com/language/APLBlos/APLBlos.htm )
  made the comment about  JCL  the Job Control Language  on IBM systems I
  never had to deal with . The comment was a line from an old Edgar Guest pulp
  poem : " It takes a lot of living to make a house a home . "

  CoSy has survived a lot o living .

  But , I find each change of hardware brings new quirks , potholes & freezers
  in Windows & Bios etc which require cerebellar level learning to stay clear
  of .

  I have Blue Book transcript with screen images of a talk & demo I gave

  you for  $25 + postage , but that`s a product of a different time , tho

I`ve attached the short invite to my ( CoSy_MidWinter_Gathering 13 ) for
  those of you around  NYC .  It will be the most interesting thing going on
  next Friday . Click the link to the full invite page .


  Yesterday , since I have not gotten the Sony I`m now using configured to
  dial the phone from DOS anymore , I changed the line in the  PFKDEFS
  function in  CoSy/APL

   from  | s 10 PFKSET ' CALL ''; :'' RDWD cursor ' |  F10
   to    | s 10 PFKSET ' p KDO Z & cursor is 1 0 + cursor & O P '  | F10

  which provides an environment in which ,
   if I tap  Enter , it "text processes" -- word wraps ;
   if I tap  F6    , it interprets the line in  CoSy/APL , inserting any
    answer in the text ;
   if I tap  F10   , it interprets the line in  K  , inserting any
    answer in the text .

  Very convenient - as long a I hit the correct key . Sorry I don`t have time
  or energy to change more than one line per month or so .


  A few days ago , in some  Libertarian  discussion of upgrading our web
  facilities , an example of  CommaSeparatedValues parsing in PERL was posted .
  It convices me  PERL  is far from understanding the insights of  APLs .

  I replied with functions for CSV conversion cleaned up from some I`ve
  created to convert  my CitiBank  account records :
--

SP : " "                       / the Space character
QT : "\""                      / the Quote character
NE : { ~ x = y }               / Not equal
QTMASK : { x | NE\ x : x = QT }    / boolean mask of quoted substrings

DRB : { ( SP = * x ) _ x : x _di & t & 1 ! t : x = SP } / Delete Redundant
                                                          / Blanks

CommaSplit : { ( , * x ) , 1 _' 1 _ x : ( 0 ,&(~ QTMASK . x)&x = ",") _ x }
        / Splits comma separated fields of CSV record .

CsvCnvrt : { .:'' + CommaSplit' DRB' x }   / convert input records to columns of
                                 / converted values ( deleting redundant blanks )
.
--
  Much more compact , of course , and more useful because of the nameable object
  nature of the result .

  I mentioned that it`s the tek of puting this stuff under a remotely hosted
  web service that I need to know .

  Hope to see some of you on the  Frying Pan .

  If you follow the path down http://cosy.com/language/cosyevo.htm , you will
  see the notion I have had since the early `80s has been an open linguistic

  ( if you don`t have your computer with you , what good is it . )
  This remains my vision .

  There should not be .  If you encounter any , post them and we`ll solve them .

  Definitely .  The problem with my moving to any specific new APL has always
  been the revenue model . Many of the things  CoSy  is good at are  too
  commonplace for professional APLer`s to drop dollars for . But selling a
  PIM built on a  $1500  buy in  ain`t an easy one .

  It`s been a long time since I printed out anything in an APL font .
  I really think the simplest and most direct way to get an understanding of
  the algorithm would be to subscribe to the CoSy-NoteComputing maillist ,
  download  CoSy  and play with , and dissect the functions .  It shouldn`t
  take more than a half hour or so to download it and get it running . It
  certainly would help me to know about any problems you ran into .

  After your first note , I edited the function  CoSyLogo  which plots n-cubes
   a bit and left it on  F8  stack as an example .  I could give you quick
  feedback on any bumps you run into .

  I think the crux of understanding the algoritm comes from seeing the
  symetries of the connection matrices - and I can`t imagine a better way to
  explore them than in the APL .


  It`s nice to hear the result may be of wider interest .  It struck me as a
  problem which might retain its interest even beyond the age of the CalComp
  pen plotter .  I have a large plot of the 9-cube which took  15644 inches
  of pen motion .



  So you`re in London , eh .  I stayed at a place near the Marble Arch after
  APL96 in Lancaster ( see http://cosy.com/language/apl96.htm ) .  If I`d
  been around a few days longer , I think I would have tried to ease in to
  one of the groups of guys hanging with strong coffee around hookahs  with
  cell phones to their ears along that street going north from the arch .

  I have communicated Jonathan Bowen and have a link in
   http://cosy.com/cosylogo.htm  which unfortunately seems stale .
  His algorithm is very clever , but less general than the Euler minimal paths
  I found an algorithm for .

  I think maybe you are failing to appreciate just how efficient APL
  notation is .  The entire algorithms , for both the cube and the simplex are
  included inline in the paper in  http://cosy.com/cosylogo.htm , and in the
  appendix at its end .

  The functions to generate the vertices of n-cubes , the Gray-code
  Hamiltonian paths , and the connectivity matrices are each 1 line .
  The iterative function to construct the Euler path is  9 , max .

  If you are involved in this sort of math , or indeed any finite computational
  math , I think this should arouse an interest in understanding this
  notation .  It`s what makes  Ken Iverson , the father of  APL  one of the
  important figures of the century .

  Generally , functions in APL are not of much use in a stand alone file .
  APL , like  Lisp , Forth , and Smalltalk operates in an interactive
  environment . One word can pass its results along to another providing
  the combinatoric flexibility of language to experiment with the concepts .

  Thus , I`d recommend again that you simply download  CoSy  and experiment
  with the functions directly .  I think you will come to appreciate why the
  few sentences of  APL  are more general and powerful than the pages of
  other languages they would expand into .

  Thanks again for your interest .  I hope this helps .

  Great to see interest in my old work .

  The  .gif  images in  http://cosy.com/cosylogo.htm  of the paper I wrote
  for the APL79 poster session are really my only "spare copies" of the
  original .

  The word  CoSyLogo  generates paths around 6 cubes viewing their main
  diagonal and a point specified in its Right Argument .
  an example with a random argument is on the  F8  command list .

  The essential algorithm is in the  function  EULER .  I believe it could be
  put into closed form , in an APL level notation , by someone who understood
  transitive closure of boolean matrices better than I do - which ain`t much .

  A major motivation for solving these problems in the first place was to
  solve something which was virtually impossible to think about in any lesser
  language than  APL .

  Understand the  APL ( it`s well factored , and you can interactively decompose
  it and step thru it in  CoSy ) , and decide for yourself whether it is worth
  exploding into one of the primitive languages .

I`ve recently uploaded a current copy of my general purpose "notecomputing"
  environment , written in open , old flat STSC DOS APL-PC .

  This venerable system continues to be useful in every day life because
  it is open code and because of many of its still unique devices and
  concepts .
  Users new to APL will find more than a thousand functions in , generally
  pretty concise , APL .

  Thus , I feel it is a good candidate to be added to anybody`s  FAQ
  listing of free intro APL environments .

  Some of the newest vocabulary provides a bridge to a process running
  Arthur Whitney`s  K  Language .

  K`s  DOS interface is so crude , that  CoSy  is a significant step upward .
  And , if you know  APL , CoSy is so malliable that substantial improvements
  in the interface will suggest themselves immediately .

  The only requirement for downoading is joining the cosy-notecomputing
  mail list so all questions comments and code are "institutionalized" .

  See  http://cosy.com/language/cosy2000.htm  for more info .

Damn , this is just the sort of thing to suk me into consuming time apparently
frivolously .

  As Blay must agree , this anagram sort of stuff is the right on the domain
where  APL
  rules .
  ( If  Math  is the  Queen of Sciences ,  APL  is the  King of Programming
Languages . )

  This problem also has a bit of history with me .  The printing of the list of
all possible
  permutations of a seat post mounted , stamped metal , bicycle rear wheel lock 
which had  6
  tabs each with 3 positions : in , out , leave-alone ;  was one of the first
tasks  I ever
  tried to solve on  Miami(Ohio) U.`s academic computer , an  IBM 1620
  ( Can`t.Add.Doesn`t.Even.Try , ( did BCD arithmatic by table lookup ) ) ,
  in 1963 .  I gave up after it crunched so long that I calculated how long it
should take .
  It would have taken well over half an hour , and I couldn`t hog the  School`s
Computer
  that long . Physics Grad students needed it , and I was just a Freshman
majoring in James
  Bond .


  Anyway , the first time I was issued a ( 4 digit ) Bank PIN , around 1982 , I
did a little
  APL to list all mnemonics associated with it . ( I still use the same  PIN . )

  In  CoSy/APL  ,  I keep around the function ( verb )  CHARSTOTELENUM  to
convert words to
  digits for autodialing :

DIGITS is '0123456789'

R is CHARSTOTELENUM STR

| Converts character strings to corresponding telephone pad numbers .
R is DIGITS , ( 3 / 2 drop DIGITS ) , '*#.'
R is R [ ( DIGITS , 'ABCDEFGHIJKLMNOPRSTUVWXY' , '*#') iota STR ]
| Circa Rochester `80__83  |1993 10 5 12 24, Bob A

        CHARSTOTELENUM 'FRE.EDOM'
373.3366

  Without creating a new word , I can just execute a couple of lines to see all
the anagrams
  for a given number :

  T0 is '1' w 'ABC' w 'DEF' w 'GHI' w 'JKI' w 'MNO' w 'PQRS' w 'TUV' w 'WXYZ'

9-5 but on 24 hr call doing film, video and audio tek stuff.  Let's
target the beginning of next week, the earliest I could arrive would be
6:30ishPM--subject to chaos.

INKEY is brilliant. CoSy takes over Moviola tomorrow, I am going to
winlink at least two copies--my desktop, and the sr tek's, Steve Ritter;
I will be using my ThinkPad under dos7.0IBM.--FM.

Hi,

It has been ages since I have used CoSy.  The battery life on my laptop
w/ NT is too short to be productive with CoSy.  I can not imagine using
95.  I just installed dos7.0 and am relearning CoSy--your help library
is helpful.  I like the speed of dos, but I need a dos browser.  I am
installing os2 again so I can have a browser and cosy.  For now dos
works perfectly.

The insert key does not put t-stack items in a job--how do I change
this.
I want to bring my jobs from the earlier compaq.
I also want to go through the exercise of communicating CoSy-to-CoSy
over the wire.

I am working at Moviola Digital, installing and setting up Avid
Workstations for the Film and Broadcast industry.  I am going to give
the Senior Tech a copy of CoSy.

I still need to optimize this dos machine.  I have had trouble zipping
CoSy under NT.  I just need to install the zip tool for dos--this should
be fail proof.

I am thinking Linux.  RedHat or a freebie?

We must get together soon--FM.
