MAIN TOPIC ABSTRACT CoSy : The essence of APL in open x86 Forth Unlike most CS(OS)^2 talks about cloud resources , CoSy is an open linguistic interface with one's computing resources . CoSy is an Open Source Project with lots of work that has been done and a lot to be done . Functionally, it is a very simple to use "day-timer" and log of all your activities . Thus reliably saving everything you do is of prime importance . And what you do may be executing an expression , including defining a new word , in the open Forth the environment is written in by tapping "F6" instead of hitting return . The Forth is written directly in x86 assembler . But at the everyday level the vocabulary is based on dynamic lists of lists evolved from APL and K . Thus 4th.CoSy is a very powerful very succinct very broad programming environment for total control of your machine . On a USBCoSyStick , you can conveniently take your environment to any WinTel computer . We will discuss What it is , Where it is , And Where it's headed -- which largely depends on where people want to take it . Browse http://CoSy.com for the entire story , and download a copy of 4th.CoSy to try on your own WinTel machine and bring with you to the MeetUp . |
SPEAKER BIOGRAPHY Bob Armstrong Bob Armstrong learned Ken Iverson and IBM Research's APL when facing the need to learn multidimensional math in grad school in the mid '70s and left FORTRAN and Algol behind for ever seduced by the ability to interactively bash his head against the computer until he understood the math . While consulting at Xerox in the early '80s learned of Chuck Moore's , also interactive , also functional , Forth , the minimal vocabulary building a dictionary capable of extending itself . 4th.CoSy melds of these two poles of programming languages into a notekeeping environment . See http://www.cosy.com/BobA/vita.htm for a more compete, well, vita . |

Both take Simplicity to the Extreme
Forth |
APL  |
- FORTH : Minimal Vocabulary to create a Dictionary capable of extending itself
- APL : Most succinct notation for the expression of application of functions to combinatoric sets of data
Forth : The minimal language
Almost immediately on any chip
In fact chips are designed with Forth as chip language
MINIMAL PARSING
WhiteSpace : The Prime Delimiter
- A
wordis Any Non Blank String of Characters
Read a word Do-It
concatenative execution: Interpreter ( -- ) Read-a-word Look-it-up-in-Dictionaryfound If Do-Itelsenumber if put-on-stackelse error ;thenthen repeat ;
word : means compile until finding a ; . That is , add following word to Dictionary with the definition being the rest of the words up to the
; Reva Forth Vocabulary
APL : The Most Expressive Language
Simplified in Arthur Whitney's K , Simplified further in 4th.CoSy
