 I ended my
4th.CoSy demo at theSilicon Valley Forth Interest Group Forth Day HangOut at Stanford U , the 3rd Saturday of November , executing each line below so the partial results would be displayed then tapping F5 to insert the
final result into the text window : s"
CoSy NEEDS MORE HEADS" >t0> rho ( |>| 22 | ) ( ) |
I've used this demo with various phrases , for instance : 'Eigen'Invite , MidWinter 96
, going back at least to the early '80s . My earliest distinct memory
of showing it was when Paul
Ellarby and I went down to Manhattan to test Philip
Van Cleave's APL68000
on a WiCat departmental computer to wean RochesterGas&Electric's
corporate model off IP Sharp time sharing ( cloud
for any millennials ) . These were among the first desktop and cabinet
sized computers capable of previously mainframe APL applications . In
any event , Vidal Sassoon was also looking at the machines and I
happened to show him this example as the sort of tek we were looking to
use on one . He thought it was neat that so much could be done with so few fairly
understandable words ( well , APL symbols denoting those words
) .
4th.CoSy is unique in being a First Person system
As I comment in the Forth Day demo , I created CoSy for my own use to give me the personal tool of thought APL provides in a notebook environment always at my finger tips .
Since its earliest forms CoSy has been about having programming , indeed programming of CoSy itself , be just a part of life . CoSy is for writing down thoughts when you have them . The thoughts may be about your human stuff , or it may be a thought about an algorithm or the definition of a key that bugs you or might be useful .
In CoSy the difference is just a keystroke .
But if there is anything on the planet as individually programmable from the chip to the APL level , please let me know .

4th.CoSy is unique in being a First Person system
As I comment in the Forth Day demo , I created CoSy for my own use to give me the personal tool of thought APL provides in a notebook environment always at my finger tips .
- CoSy is not a Third Person
system written by programmers to satisfy a boss's notions of what might
be marketable .
- CoSy is for my control of my computing resources .
- CoSy
provides a
1 = 1relationship between me and any minds like enough to mine to find CoSy an indispensable aid in their everyday business of life .
Since its earliest forms CoSy has been about having programming , indeed programming of CoSy itself , be just a part of life . CoSy is for writing down thoughts when you have them . The thoughts may be about your human stuff , or it may be a thought about an algorithm or the definition of a key that bugs you or might be useful .
In CoSy the difference is just a keystroke .
- Tapping
enteris just a carriage return
- Tapping
F6tells CoSy to do whatever the line under the cursor says displaying the result ( which must be a CoSy object or nothing ) .
And currently :
- Tapping
sF6causes the line to be executed in Forth without automatic output .

sockets
vocabulary to the CoSy
level to enable communication between multiple instances of 4th.CoSy , and so I can slave my legacy
K.CoSy
accounting system to my 4th.CoSy working environment . I couldn't have stolen the time to create 4th.CoSy if it were not for K.CoSy's very flexible and powerful accounting functionality with typical CoSy
logs hyperlinked to associated ledgers . But the limitations of the K environment , for instance its lack of cut%paste with the outside world , and Kx's very different obsessions ( K.CoSy may well be the only interactive workspace like environment ever created in K ) drove me to finally figure out how to roll my own APL from a chip language up in FORTH .Now the foundation of 4th.CoSy is mature and stable enough that it can evolve exponentially faster with , in the spirit of my most esteemed mentor , Donald T Campbell's fish scale model of omniscience

#Ideas 
Important ideas :- All objects are lists
- Items of lists may themselves be lists
- modulo indexing
- dictionary ( names ; values )
Rtree dictionary
metalink on every object- Currently directly executed in FORTH
- ( (bijective )
transformation > < allocated reference counted lists of
lists and a linear file form
- reference counting "algebra" on lists of lists to handle
various situations
- Stack Frame vocabulary
- Atomic Apply
