	stmt (Site not responding. Last check: 2007-10-15)
		A null statement is useful to carry a label just before the } of a compound statement and to supply a null body to an iteration statement such as a while statement (_stmt.while_).
		Transfer out of a loop, out of a block, or back past an ini- tialized variable with automatic storage duration involves the destruction of variables with automatic storage duration that are in scope at the point transferred from but not at the point transferred to.
		6.6.2 The continue statement [stmt.cont] 1 The continue statement shall occur only in an iteration-statement and causes control to pass to the loop-continuation portion of the small- est enclosing iteration-statement, that is, to the end of the loop.

	PEP 340 -- Anonymous Block Statements
		I should clarify that using a generator to "drive" a block statement is really a separable proposal; with just the definition of the block statement from the PEP you could implement all the examples using a class (similar to example 6, which is easily turned into a template).
		Block iterators also have the opportunity to execute the controlled code more than once (or not at all), catch exceptions, or receive data from the body of the block statement.
		When a generator is used as a block iterator, the yield statement tells the Python interpreter to suspend the block iterator, execute the block statement body, and resume the block iterator when the body has executed.

	[Chapter 4] 4.3 Statements
		Every simple statement must end in a semicolon, unless it is the final statement in a block.
		Compound statements are defined in terms of blocks, not statements, which means that braces are required.
		statement repeatedly executes a block as long as its conditional expression is true.

	Perl 5 by Example: Statements (Site not responding. Last check: 2007-10-15)
		A statement block is a group of statements surrounded by curly braces.
		Using a statement block does not change the program execution in any way; it simply is a visual device to mark sections of code and a way to create local variables.
		Statement blocks are also good to use when you temporarily need to send debugging output to a file.

	Statement
		Statements define the flow of a script, known as "program flow." A statement, like a fully grammatical English sentence, is made up of smaller expressions which, altogether, evaluate into a cogent meaning.
		Blocks of statements are used, for example, in functions and conditionals.
		In similar fashion as the do...while statement, the while statement executes its statement block as long as the condition is true.

	GAWK:awk_language:statements (Site not responding. Last check: 2007-10-15)
		A conditional statement in awk uses the same syntax as for the 'C' programming language: the 'if' keyword, followed by an expression in parentheses, followed by a statement--or block of statements enclosed within braces ({})--which will be executed if the expression is true but skipped if it's false.
		The 'continue' statement is useful in a compound (block) statement; when executed, it effectively skips the rest of the block so that the increment-expression (only for for-loops) and loop-termination expression can be re-evaluated.
		The 'break' statement, when executed, effectively skips the rest of the block and also treats the test expression as if it were false (instead of actually re-evaluating it).

		statement if you have a large number of loop initializers or loop iterators, because statements that contain a large number of comma operators are difficult to read.
		This statement tells the Perl interpreter to terminate executing the loop and to continue with the first statement after the loop, which is line 18.
		statement must be followed by a statement block, which is a collection of zero or more statements enclosed in brace characters.

	CHAPTER 7 - Blocks and Statements
		There are two primary blocks defined for a T program: the main block, which is explained in section (§7.1), and statement blocks which are explained in section (§7.2).
		statement in the main block is executed or the end of the main block is reached (or a run-time error is encountered).
		The scope of a variable declared in the main block is from its declaration point to the end of the main block.

		That is, it consists of a sequence of statements enclosed between a pair of braces, "{" and "}".
		An empty block consists of nothing but an empty pair of braces.) Block statements usually occur inside other statements, where their purpose is to group together several statements into a unit.
		There is one place where a block is required: As you might have already noticed in the case of the main subroutine of a program, the definition of a subroutine is a block, since it is a sequence of statements enclosed inside a pair of braces.

	Statement (programming) - Wikipedia, the free encyclopedia
		In most languages statements contrast with expressions in that statements do not return results and are executed solely for their side effects, while expressions always return a result and often do not have side effects at all.
		In languages which mix imperative and functional styles, such as the Lisp family, the distinction between expressions and statements is not made: even expressions executed in sequential contexts solely for their side effects and whose return values are not used are considered 'expressions'.
		Most programming languages do not allow new statements to be created during program execution (Snobol 4 is a language that does), or existing statements to be modified (Lisp is well known for supporting self modifying code).

	Conditionals - Perl.
		If the expression had a false value, then that statement block would not be executed and the script would go onto the next line of code.
		ELSIF statements can be used when you have more than one expression to evaluate and to select the correct statement block to execute.
		When any statement block within the control structure is executed, the control is taken out of the IF area and continues onto the next line of code.

		The block statement begins with a label (see Identifier) which is not optional, followed by a colon and the keyword block.
		After the block header may optionally appear a number of Block Declarative Items, which are used to declare elements needed within the body of the block statement.
		A block statement can represent an independent portion of a design, and communicate with its environment using its own port map and generic map, as indicated in the Block Header syntax.

	Statement block - Wikipedia, the free encyclopedia
		In computer programming, a statement block (or code block) is a section of code which is grouped together, much like a paragraph; such blocks consist of one, or more, statements.
		Blocks often define the scope of the identifiers used within.
		In languages such as Smalltalk, blocks are objects in their own right, extended with a reference to their environment of definition, i.e.

	DO statement
		The test occurs at the bottom of the loop, and the statement block is executed again if the expression is true, for the WHILE case, or false, for the UNTIL case.
		If you use a conditional clause on the LOOP statement, the condition is evaluated at the bottom of the loop, meaning that the statement block will be executed at least once.
		In both of these cases, the statement block will be executed at least once; the loop test is performed at the bottom of the loop.

	GPL p8
		Recall in p7 that when parsing a statement block you created a new Statement_block and pushed it onto the statement block stack when you parsed the "{" and when you parsed the "}" you popped it off the stack and sent it up the parse tree (i.e.
		This way each statement you parsed (while inside the block) could be inserted into the Statement_block at the top of the stack.
		Thus you will be filling in the statement block that was created in the forward statement instead of creating a new one.
