	The LEX & YACC Page
		Lex source is a table of regular expressions and corresponding program fragments.
		The program fragments written by the user are executed in the order in which the corresponding regular expressions occur in the input stream.
		An input language may be as complex as a programming language, or as simple as a sequence of numbers.

	A lexical analyzer generator for Standard ML. Version 1.6.0, October 1994
		Lex, a programming tool for the Unix system, is a successful solution to the general problem of lexical analysis.
		Lex produces a program for a function that can be used to perform lexical analysis.
		It executes the program fragment associated with the class, and sets the current position in the input stream to be the character after the word.

	Build code with lex and yacc, Part 2: Development and troubleshooting (Site not responding. Last check: )
		A more powerful tool is exclusive states, in which only rules matching the exclusive state can be matched (this is not supported in all versions of lex, but should be available in anything modern).
		It used to be that using multiple parsers within a single program required a fair amount of careful tuning of the files generated by lex and yacc.
		The Lex and Yacc Page, or "The asteroid to kill this dinosaur is still in orbit," has a number of interesting historical references as well as very good lex and yacc documentation.

	The Flex Manual Page
		Furthermore, existing lex programs sometimes access yytext externally using declara- tions of the form: extern char yytext[]; This definition is erroneous when used with %pointer, but correct for %array.
		Some existing lex programs depend on this behavior, even though it is not compliant with ANSI C, which does not require stdin and stdout to be compile-time constant.
		- flex scanners are not as reentrant as lex scanners.

	Jumpstart your Yacc...and Lex too! (Site not responding. Last check: )
		A Lex program is divided into three sections: the first section has global C and Lex declarations, the second section has the patterns (coded in C), and the third section has supplemental C functions.
		The third and final section of programming in Lex covers C function declarations (and occasionally the main function) Note that this section has to include the yywrap() function.
		Lex has several functions and variables that provide different information and can be used to build programs that can perform complex functions.

	BASIC Programming and Chipmunk Basic Home Page
		BASIC (an acronym for "Beginner's All-purpose Symbolic Instruction Code") is the name of a family of related high-level programming languages, developed, circa 1963 at Dartmouth College, to provide an accessible and easy-to-learn environment for non-science students to understand and use computers.
		In the early 1980's, the Basic programming language was built-in to the majority of personal computers sold.
		Chipmunk Basic was featured in the Programming Paradigms column of the December 1995 issue of Dr.

		Lex is a lexical analyzer generator for the UNIX operating system, targeted to the C programming language.
		However, to support further extensions on the CsLex tool, all internal processing of characters is done using the 16-bit C# character type, although the full range of 16-bit values is not supported.

	Using lex with yacc
		If you work on a compiler project or develop a program to check the validity of an input language, you may want to use the UNIX system program tool yacc(CP).
		Whether or not you plan to use lex with yacc, this part is useful because it covers information of interest to all lex programmers.
		No matter what kind of parser you are using, the lexical analyzer generated by lex is invoked through a call to the function yylex().

	lex UNIX Software Tool
		lex is a Unix software tool, often used in conjunction with yacc and compiler writing, that generates programs for simple lexical tasks.
		Yet lex may be used as a standalone utility generating code automatically and more reliably than a programmer might do.
		lex is easy to learn, especially if one is familiar with the syntax of C and regular expressions.

	Embedded.com - Lex and Yacc for Embedded Programmers
		Lex and yacc are free development tools that help you write software in C or C++ that interprets or transforms structured input.
		Although lex generally produces scanners that are faster than hand-coded equivalents, the parsers generated by yacc are typically slower than a well-designed, hand-coded equivalent.
		Although lex and yacc are generally considered to be UNIX utilities, versions exist for a variety of platforms.

		Java CUP is a parser generator for Java originally written by Scott Hudson of Georgia Tech University, and maintained and extended by Frank Flannery, Dan Wang, and C. Scott Ananian.
		However, to support further extensions on the JLex tool, all internal processing of characters is done using the 16-bit Java character type, although the full range of 16-bit values is not supported.
		One of the biggest complaints about table-driven lexical analyzers generated by programs like JLex is that these lexical analyzers do not perform as well as hand-written ones.

	Meta Programming
		A metaprogram is a program that manipulates other programs (or itself) as its data.
		Writing a translator for a general purpose programming language is outside the scope of this discussion--we all know why this is done, and agree that it should be.
		The basic problem is that any general-purpose programming language without a metaprogramming model that is designed to be as pleasant and expressive as the language itself will eventually frustrate the user with it's limitations.

	Learning the GNU development tools:
		If these programs are modified by someone else and passed on, we want their recipients to know that what they have is not what we distributed, so that any problems introduced by others will not reflect on our reputation.
		The C programming language is the native language of GNU, and the GNU coding standards encourage you to program in C. The main advantages of C are that it can be compiled with the system's native compiler, many people know C, and it is easy to learn.
		If you write a program whose use involves editing some type of input files, it is very much appreciated by the community if you also write an Emacs mode for thet file and distribute it with your program.

	Looking for lex and yacc for Java? You don't know Jack - Java World
		Sun has released Jack, a new tool written in Java that automatically generates parsers by compiling a high-level grammar specification stored in a text file.
		With the help of my wife to be, I had written a simple compiler that could turn programs written in a language made up for the class into executable programs.
		Lex built lexical analyzers from regular expressions, and yacc reduced a grammar specification into a table-driven compiler that could produce code when it had successfully parsed productions from that grammar.
