 programming language. The Columbia Encyclopedia, Sixth Edition. 2001-05
All computers operate by following machine language programs, a long sequence of instructions called machine code that is addressed to the hardware of the computer and is written in binary notation (see numeration), which uses only the digits 1 and 0.
PL/1 [Programming Language 1], developed in the late 1960s by the IBM Corp., and ADA [for Ada Augusta, countess of Lovelace, biographer of Charles Babbage], developed in 1981 by the U.S. Dept. of Defense, are designed for both business and scientific use.
With some languages, such as C or Pascal, the program is turned into a separate machine language program by a compiler, which functions much as an assembler does.

 Statistical programming with R | Lambda the Ultimate
R is a suite of software facilities for data manipulation, calculation and graphical display, which is quite useful for statistical analysis.
R and S were touched on fairly briefly in the LtU discussion about Regression Analysis.
In the meantime, there's a timely article on Analyzing Baseball Stats with R for those would be sabermetricians - though probably not in time to save the Cardinals from their demise.

 Statistical programming with R: Part 1. Dabbling with a wealth of statistical facilities
The R environment is not intended to be a programming language per se, but rather an interactive tool for exploring data sets, including the generation of a wide range of graphic representations of data properties.
R is available in compiled form for many computer platforms: Linux, Windows, Mac OS X, and Mac OS Classic.
Nonetheless, R is generally stable, fast, and comes with an absolutely amazing range of statistical and math functions.

 The Scheme Programming Language
Scheme was one of the first programming languages to incorporate first class procedures as in the lambda calculus, thereby proving the usefulness of static scope rules and block structure in a dynamically typed language.
Scheme is also the first programming language to support hygienic macros, which permit the syntax of a block-structured language to be extended reliably.
PLT Scheme is an umbrella name for a family of implementations of the Scheme programming language.

 The R Programming Language   (Site not responding. Last check: 2007-09-10)
programming languaged used "Teutonic" runes (which, contrary to popular belief, were invented by the Druids for this purpose) for the elements of the language.
Refer to the illustration for a key of the elements of the language decyphered thus far.
The language is notable for it's lack of a FOR statement (which is approximated by using GOTO branching) and it's ambiguous use of the equals sign and parentheses.

 Define programming language generations - a definition from Whatis.com - see also: 1GL, 2GL, 3GL, 4GL, 5GL, program ...
In the computer industry, these abbreviations are widely used to represent major steps or "generations" in the evolution of programming languages.
1GL or first-generation language was (and still is) machine language or the level of instructions and data that the processor is actually given to work on (which in conventional computers is a string of 0s and 1s).
Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components.

 FreeTechBooks.com - The Scheme Programming Language, Third Edition   (Site not responding. Last check: 2007-09-10)
Scheme is now a complete general-purpose programming language, though it still derives its power from a small set of key concepts.
Early implementations of the language were interpreter-based and slow, but some current Scheme implementations boast sophisticated compilers that generate code on par with code generated by the best optimizing compilers for lower-level languages such as C and Fortran.
The reader is expected to have had some experience programming and to be familiar with terms commonly associated with computers and programming languages.

 What is programming language? - A Word Definition From the Webopedia Computer Dictionary
Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions.
Assembly languages are similar to machine languages, but they are much easier to program in because they allow a programmer to substitute names for numbers.
The choice of which language to use depends on the type of computer the program is to run on, what sort of program it is, and the expertise of the programmer.

 About APL (A Programming Language)
In the verbosity of most programming languages, the "forest" gets lost in the proliferation of "trees": The wordiness of the implementation tends to foreground itself vis-à-vis the "play" of exploring computational possibilities.
I used to describe it as a: "fascist programming language", because it is dictatorially rigid.
Build a vector the same length as R, but with 1 in each place where the corresponding number in R is in the table [true=1], and 0 where the corresponding number is not [false=0] (0, 0, 1, 0, 1).

 A Linguistics Oriented Programming Language   (Site not responding. Last check: 2007-09-10)
The interesting property of these programs is that two of them were written in quite a short space of time by students with no experience in either LINGOL or linguistics.
The program consisted of a page of grammar and semantics, a page of dictionary and a page of useful functions for conjugating verbs, arranging agreements of articles and adjectives, performing liason and so on, so it was not particularly large.
In particular, in the programming methodology to be described, large items are gradually built up from smaller ones, and it is tricky to cast this in a stimulus-response format.

 The Icon Programming Language
Icon is a derivation of SNOBOL, a language originally designed by Bell Telephone Laboratories in the early 60s to promote development of string and structure intensive applications.
The name Icon was chosen before the term "icon" became popular for GUI images in use today and does not stand for anything correlating to the language (apparently it is just a catchy name).
Icon is a high-level, imperative, procedural language especially useful for processing strings and structures.

 Mixed Language Programming
The topic of mixed language programming, or inter language communication, has in recent years received greater attention than before.
This is partly due to the successful acceptance of the high-level languages Ada, C and Pascal, together with the strong survival of the classical languages Cobol and Fortran.

 Amazon.com: The C Programming Language (2nd Edition): Books: Brian W. Kernighan,Dennis Ritchie,Dennis M. Ritchie   (Site not responding. Last check: 2007-09-10)
The book focuses on the language itself - this is no hands-on book (no explanations on how to use this compiler or that debugger, though it is a little biased toward Unix) in a clear, concise, and thorough way covering all of the language and it's standard libraries.
I especially liked the excercises (the solutions come in a seperate volume) and the C source code examples of how some of the library routines are (or may be) implemented.
This book is *not* for people who study C as their first programming language (those would be better served with a pair of books - a first course in programming and compiler guide).

 Language Oriented Programming.
Via Andres Aguiar I stumbled into one of the most insightful articles I've read in the last couple of months: Language Oriented Programming, The Next Programming Paradigm, written by Sergey Dmitriev of Jetbrains.
It brilliantly describes one of the biggest problems of today's software engineering: that there is no (or at most weak) connection between what we're intented to develop and what's actually developed; you need to reverse engineer the code written to understand which functionality it represents, while it should be that what you intended (i.e.
