System Feature
	precedence

Purpose
	Specifies order in which operators are executed in expression.

Syntax
	There is no explicit syntax. Precedence is implicit.

Description
	Within an expression, we recommend generous use of parentheses (), which will ensure
	that the expression is evaluated exactly as you intended. There is no limit on how many
	parentheses can be used, and no limit on how many levels of parentheses can be used.

	Without parentheses, operators are executed in the followning order of precedence.

		and	AND	N	N	N	Y
		or	OR	N	N	N	Y	<===== LOWEST PRECEDENCE

	Operator of highest precedence is executed first.
	Operator of lowest precedence is executed last.
	Operators of higher precedence are executed before operators of lower precedence.
	Among two operators of same precedence at the same level, operator on the left
	is executed before the operator on the right.
		
Restrictions
	

Valid Examples
	5 + 3 * 2
	3 and 2 are multiplied first, then the result is added
	to 5. Final result: 11.

	 $x < 7 AND $y ** 2 - 4 > 0
	will be interpreted as
	( ($x < 7) AND ( ( ($y ** 2) - 4) > 0) )
	

Invalid Examples
	1024 / 2 * $x
	$x will be multiplied by 2 and then 1024 will be
	divided by the result. If you meant to multiply the result of (1024/2) by $x,
	use
	(1024 / 2) * $x .
