  NewtonScript - Wikipedia, the free encyclopedia
It is heavily influenced by the Self computer language, but extended to be more suited to the personal digital assistant's needs.
NewtonScript is also one of the conceptual ancestors (together with Smalltalk, Self, Act1, Lisp and Lua) of a recently created general-purpose programming language called Io.
NewtonScript employs an inheritance model called differential inheritance where only the differences with its parent prototype are stored in a list of properties (known as slots in Io).

NewtonScript is an prototype based programming language created to write programs for the Apple Newton.
The Newton was originially going to be programmed in the new Dylan programming language, but a lengthy series of delays combined with NIH eventually led to it being adbandoned.
Finally the "inheritance" system in the normal Self engine had a single parent object, whereas GUI's typically have two -- one for the objects and another for the GUI layout that is typically handled via the addition of a slot in some sort of GUI-hierarchy object (like View).

 Self programming language - Wikipedia, the free encyclopedia
It was used primarily as an experimental test system for language design in the 1980s and 1990s; however, as of July of 2006, Self is still being actively developed as part of the Klein project which is a Self virtual machine written entirely in Self.
Their objective was to push forward the state of the art in object-oriented programming language research, once Smalltalk-80 had gone out of the labs and began to be taken seriously by the industry.
Dynamic languages such as Smalltalk allowed for this sort of change via well-known methods in the classes; by changing the class, the objects based on it would change their behaviour.

Written primarily by Walter Smith, the language was a part ofthe Newton Toolkit, introduced along with the Newton on August 1993.
Since the language would be used for the entire system, as opposed to just running on anexisting operating system, it needed to run as fast as possible.
Finally the "inheritance" system in the normal Self engine had a single parent object, whereas GUI 's typically have two -- one for the objects and another for the GUI layout that is typically handled via theaddition of a slot in some sort of GUI-hierarchy object (like View).

The language is formally defined in the Revised Report on the Algorithmic Language Algol 68 by A. van Wijngaarden et al using a VW (2 level) grammar.
Data structured languages are those in which the data structure is a main organizing principle, knowledge representation, model, for data and logic (code, programs) alike, in which both are stored and operated on, i.e., program data and logic are structured and operated on in the same way.
Simula is an extension of the ALGOL 60 language, and is the language that introduced to programming the ideas of classes, objects, inheritance, and dynamic binding, making it is the first, original object-oriented language.

 dylan programming language -
It was originally created by a group led by Apple Computer, and intended for use with Apple's Newton computer, but their implementation did not reach sufficient maturity in time, and they instead developed NewtonScript for that project.
In addition the namespace/class system in most languages defines a single unit that must be used as a whole, if you want to use the String.concat function, you must import and compile against all of String, or the namespace that includes it.
In most languages when the program is compiled the to-string for dylan programming language is looked up and replaced with a pointer (more or less) to the method.

 The Encyclopedia of Computer Languages   (Site not responding. Last check: 2007-11-01)
Object-oriented languages were just starting to enter the mainstream (even C++ was not yet the industry darling it is today), and there were a lot of interesting new languages to learn about and evaluate.
Although it was clearly impractical as a system language (it took several years for the SELF compiler to reach its present impressive state), its audacious simplicity made an impression that the more andquot;seriousandquot; languages did not.
The NewtonScript documentation avoids such a direct description of the calling mechanism because we find very few people are interested in such details, and in fact the demands of speed draw the implementation away from such a direct approach, but here you can see the elegance of the original concept.

NewtonScript NewtonScript is an prototype based programming language created to write programs for the Apple Newton.
Prototype-based programming Prototype-based programming is a style and subset of object-oriented programming in which classes are not present, and behaviour reuse (known as inheritance in class-based languages) is accomplished through a process of cloning existing objects which serve as prototypes.
