	Expressions
		Each expression occurs in the declaration of some (class or interface) type that is being declared: in a field initializer, in a static initializer, in a constructor declaration, or in the code for a method.
		Within an FP-strict expression, all intermediate values must be elements of the float value set or the double value set, implying that the results of all FP-strict expressions must be those predicted by IEEE 754 arithmetic on operands represented using single and double formats.
		A parenthesized expression is a primary expression whose type is the type of the contained expression and whose value at run time is the value of the contained expression.

		An S expression may be a symbol, a number, or a series of S expressions in parentheses.
		It is followed by an S expression with the function parameters, and an S expression which is the body of the funciton.
		As long as the user inputs an S expression to evaluate, it is passed to eval and the result printed.

	Expressions & Sayings (S) (Site not responding. Last check: 2007-10-31)
		This expression, which means to have to use someone or something of poor or inferior quality because that is all that is available, refers to the fact that people will only scrape out the bottom of an empty barrel if they have no more full ones.
		Despite this antiquity the expression was not used in its modern secular sense until the 19th century, probably as a result of increased British familiarity with Islam during the period of empire.
		To complete this transformation of a rustic expression into a nautical-sounding one, the rather extravagant and unconvincing idea of 'losing' an entire ship for the sale of a small economy was changed to 'spoiling' and the now familiar version emerged in the mid-19th century.

	O'Reilly Media -- Bookstore: Mastering Regular Expressions
		Regular expressions, a powerful tool for manipulating text and data, are found in scripting languages, editors, programming environments, and specialized tools.
		Regular expressions are not a tool in and of themselves, but are included as part of a larger utility.
		Regular expressions are not used in a vacuum.

	Variables and Expressions
		The latter method is preferred by many due to its greater clarity, and because it supports an expression syntax nearly identical to that in many other languages.
		Expressions are used to perform one or more operations upon a series of variables, literal strings, and/or literal numbers.
		Force an expression: An expression can be used in a parameter that does not directly support it (except an OutputVar or InputVar parameter such as those of StringLen) by preceding the expression with a percent sign and a space or tab.

	Syntax and Semantics
		When the first element of a list is a symbol naming a special operator, the rest of the expressions are evaluated according to the rule for that operator.
		It's easy to lose track when you're typing expressions at the REPL because the two phases happen one after another and the value of the second phase is immediately returned.
		s at the end may seem forbidding, but as long your code is properly indented the parentheses should fade away--no need to give them undue prominence by spreading them across several lines.

	Recursive Functions of Symbolic Expressions (Site not responding. Last check: 2007-10-31)
		Since many of the symbolic expressions with which we deal are conveniently expressed as lists, we shall introduce a list notation to abbreviate certain S-expressions.
		Since we regard the expressions with commas as abbreviations for those not involving commas, we shall refer to them all as S-expressions.
		The expressions representing these functions are written in a conventional functional notation.

		The arguments are =over 4 =item[1] the name of the S function or an RFunctionReference object obtained from an earlier computation =item[2] an arbitrary number of arguments which are converted to S values and used as arguments to the S function, in the same order they are giving here.
		If the value of this call is assigned in Perl or passed on to another call, the return value from the S function is converted to a Perl object.
		However, it is convenient for evaluating self-contained S expressions such as interactive queries of the state of the S session, defining functions and methods, etc.

		is a direct consequence of some of the preceding expressions by virtue of one of the rules of inference.
		A decidable proof system is, roughly speaking, one for which a machine can be advised to test its expressions for theoremhood, whereas, in an undecidable theory, ingenuity is required to determine whether the expressions are theorems.
		A proof system, for which there is a mechanical method for determining, given any expression A of the system, not only whether there is a proof of A, but also of finding such a proof, is called syntactically decidable; otherwise it is syntactically undecidable.

	XML Schema Part 2: Datatypes: Regular Expressions
		A regular expression R is a sequence of characters that denote a set of strings L(R).
		When used to constrain a lexical space, a regular expression R asserts that only strings in L(R) are valid literals for values of that type.
		These characters have special meanings in regular expressions, but can be escaped to form atoms that denote the sets of strings containing only themselves, i.e., an escaped metacharacter behaves like a normal character.

	Comparing XLANG/s and C#
		The expression editor, in the first instance, edits a representation of your expression held in the designer XML in the.odx file, and because the editor thinks it is illegal to use unqualified type names, it places an #error directive within the actual XLANG/s code.
		Each scope is represented at runtime by a scope context object, and each variable declared at that scope level is represented by an internal field of that class.
		When an inner scope contains an expression that uses a variable from an outer scope, the orchestration code generator generates a field in the inner scope class of the same name and type as the corresponding field on the outer scope class.

	S Documentation Engine (Site not responding. Last check: 2007-10-31)
		Computations for online help are a combination of S computations on these objects and other computations using a mapping of documentation objects to the SGML language.
		The advantage of this organization is that both the S and the SGML versions of the documentation are capable of representing the structure of the information.
		The S side of the computations can map information from general S objects into the documentation (for example, using objects that represent S expressions), while the SGML side can organize both structural information about the document (what information is allowed and where) and also rendering information when web-based tools are used to view the documentation.

		A page template may therefore contain anything that targeted clients will accept, with the addition of five XML tags and one 'pcdata' expression token, as mark-up for the python code that defines the coupling between the presentation to the application data.
		Xyaptu is python-centric, in the sense that the XML tags offered reflect python constructs (such as python expressions, statements, opening and closing blocks) and not particularly constructs typically identified in web page templates.
		Python expressions are also mapped to a 'pcdata' token, to allow the use of python expressions also in places where tags are not allowed, i.e.

	XML.com: Regular Expression Matching in XSLT 2
		For example, to replace all dollars and cents expressions with the string "$xx.xx", you can assemble a regular expression to show that you want to search for any string consisting of a dollar sign followed by one or more numeric digits, a period, and then two more digits.
		Regular Expression Syntax section of the XQuery 1.0 and XPath 2.0 Functions and Operators specification describes these flags in more detail; it also provides g background on the roots of the XPath regular expression support in the W3C Schema specification.
		In regular expressions, a period can be used to represent any character (as we saw at the very beginning of this regular expression) but we're looking for an actual period here, so it has a backslash like the one before the dollar sign.

		If matching regular expressions is analogous to a walk in the woods, then the tools discussed in Part 1 are analogous to topo maps and a compass, basic tools we use all the time.
		If the code expression is a conditional, the code is evaluated and the result (i.e., the result of the last statement) is used to determine truth or falsehood.
		The pattern code expression is like a regular code expression, except that the result of the code evaluation is treated as a regular expression and matched immediately.

		Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated.
		If you don't know what a regular expression is then you have no need for this book, but if you have ever worked with regular expressions then you are in for a treat with this book.
		After a basic introduction covering the most common tasks regular expressions are used for (substitution, selection, wild cards, etc.) the author delves into examples of regular expressions in Perl, and follows that with a section discussing some of the variations in regular expressions as implemented in different languages and common programs.
