 Joy programming language -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-21)
Joy is based on composition of functions rather than (Click link for more info and facts about lambda calculus) lambda calculus.
In joy, everything is a function that takes a (An orderly pile) stack as an argument and returns a stack as a result.
Joy is the purest implementation of the (Click link for more info and facts about lambda calculus) lambda calculus as a programming language, but it still manages to be practical and potentially useful, unlike the otherwise similar (Click link for more info and facts about unlambda) unlambda.

 CSCI524 Programming Language Principles
Languages are classified as low level if they are close to machine code and high level if each language statement corresponds to many machine code instructions (though this could also apply to a low level language with extensive use of macros, in which case it would be debatable whether it still counted as low level).
Orthogonality in a programming language means that a relatively small set of primitive constructs can be combined in a relatively small number of ways to build the control and data structures of the language.
C is often described, with a mixture of fondness and disdain, as "a language that combines all the elegance and power of assembly language with all the readability and maintainability of assembly language".

 RE: Joy and Concatenative Programming
Programming in Joy is like programming with categorical combinators, but ignoring the types.
Saying that Joy programs "lack variables" is pretty close to saying that its free variable environments are linearly ordered.
So, though the ordering is really irrelevant, every Joy program must pick one, and that can be understood as non-declarative, since it has nothing to do with the result of the program.

 Forth programming language : Forth   (Site not responding. Last check: 2007-10-21)
Forth is a computer programming environment developed by Chuck Moore[?] then at the US National Radio Astronomy Observatory (NRAO[?]) during the 1960s, and later formalized as a programming language in 1977, and standardized by ANSI in 1994.
Programming is done by extending the language with 'words' (named subroutines), which become part of the language once defined.
Due to the simplicity to add and use small machine code definitions to the language and use those in an interactive high level programming environment, the Forth language has been popular as a development language for embedded systems and as a vehicle for instrument control[?].

 Who Cares About Elegance? The Role of Aesthetics in Programming Language Design
Programming language design is a comparatively new activity - it has existed for less than half a century, so it is often worthwhile to look to older design disciplines to understand better this new activity.
Similarly in programming language design, the limitations of the analytic approach often force us to make a choice between an under-engineered design, in which we run the risk of unanticipated interactions, and an over-engineered design, in which we have confidence, but which is inefficient or uneconomical.
The programming language should not be a hindrance, but should serve more as a collaborator, encouraging programmers to do their jobs better.

 Joy programming language - Wikipedia, the free encyclopedia
The Joy programming language is a purely functional programming language that was produced by Manfred von Thun of Latrobe University in Melbourne, Australia.

It is always correct for an implementation of the Java programming language to use an element of the float value set to represent a value of type float; however, it may be permissible in certain regions of code for an implementation to use an element of the float-extended-exponent value set instead.
All exceptions in the Java programming language are precise: when the transfer of control takes place, all effects of the statements executed and expressions evaluated before the point from which the exception is thrown must appear to have taken place.

 The Befreak Programming Language
Befreak is a purely reversible two-dimensional programming language.
This is a natural phenomenon in reversible programming, since if we were running the loop backwards, we need to know at what point we are done so we can "exit" the loop (through the entrance).
One of the neat things about a reversible programming language is the ability to run code backwards.
