Flash Lite 1.x ActionScript Language Reference

Flash Lite Operators

This section describes the syntax and use of Adobe's Macromedia Flash Lite 1.x ActionScript operators. All entries are listed alphabetically. However, some operators are symbols and are alphabetized by their text descriptions.

The operators in this section are summarized in the following table:

Operator	Description
`add (string concatenation)`	Concatenates (combines) two or more strings.
`+= (addition assignment)`	Assigns `expression1` the value of `expression1` `+` `expression2`.
`and`	Performs a logical AND operation.
`= (assignment)`	Assigns the value of `expression2` (the operand on the right) to the variable or property in `expression1`.
`/* (block comment)`	Indicates one or more lines of script comments. Any characters that appear between the opening comment tag (/) and the closing comment tag (/) are interpreted as a comment and ignored by the ActionScript interpreter.
`, (comma)`	Evaluates `expression1`, then `expression2`, and returns the value of `expression2`.
`// (comment)`	Indicates the beginning of a script comment. Any characters that appear between the comment delimiter (//) and the end-of-line character are interpreted as a comment and ignored by the ActionScript interpreter.
`?: (conditional)`	Instructs Flash Lite to evaluate `expression1`, and if the value of `expression1` is `true`, the operator returns the value of `expression2`; otherwise, it returns the value of `expression3`.
`-- (decrement)`	Subtracts 1 from `expression`. The pre-decrement form of the operator (`--expression`) subtracts 1 from `expression` and returns the result as a number. The post-decrement form of the operator (`expression--`) subtracts 1 from `expression` and returns the initial value of `expression` (the value before the subtraction).
`/ (divide)`	Divides `expression1` by `expression2`.
`/= (division assignment)`	Assigns `expression1` the value of `expression1 / expression2`.
`. (dot)`	Used to navigate movie clip hierarchies to access nested (child) movie clips, variables, or properties.
`++ (increment)`	Adds 1 to `expression`. The expression can be a variable, element in an array, or property of an object. The pre-increment form of the operator (`++expression`) adds 1 to `expression` and returns the result as a number. The post-increment form of the operator (`expression++`) adds 1 to `expression` and returns the initial value of `expression` (the value before the addition).
`&& (logical AND)`	Evaluates `expression1` (the expression on the left side of the operator) and returns `false` if the expression evaluates to `false`. If `expression1` evaluates to `true`, `expression2` (the expression on the right side of the operator) is evaluated. If `expression2` evaluates to `true`, the final result is `true`; otherwise, it is `false`.
`! (logical NOT)`	Inverts the Boolean value of a variable or expression. If `expression` is a variable with the absolute or converted value of `true`, the value of `!expression` is `false.` If the expression `x && y` evaluates to `false`, the expression `!(x && y)` evaluates to `true`.
`\|\| (logical OR)`	Evaluates `expression1` and `expression2`. The result is `true` if either or both expressions evaluate to `true`; the result is `false` only if both expressions evaluate to `false`. You can use the logical OR operator with any number of operands; if any operand evaluates to `true`, the result is `true`.
`% (modulo)`	Calculates the remainder of `expression1` divided by `expression2`. If an `expression` operand is non-numeric, the modulo operator attempts to convert it to a number.
`%= (modulo assignment)`	Assigns `expression1` the value of `expression1 % expression2`.
`*= (multiplication assignment)`	Assigns `expression1` the value of `expression1 * expression2` .
`* (multiply)`	Multiples two numeric expressions.
`+ (numeric add)`	Adds numeric expressions.
`== (numeric equality)`	Tests for equality; if `expression1` is equal to `expression2` , the result is `true`.
`> (numeric greater than)`	Compares two expressions and determines whether `expression1` is greater than `expression2` ; if it is, the operator returns `true`. If `expression1` is less than or equal to `expression2` , the operator returns `false`.
`>= (numeric greater than or equal to)`	Compares two expressions and determines whether `expression1` is greater than or equal to `expression2` `(true)` or whether `expression1` is less than `expression2` `(false)`.
`<> (numeric inequality)`	Tests for inequality; if `expression1` is equal to `expression2` , the result is `false`.
`< (numeric less than)`	Compares two expressions and determines whether `expression1` is less than `expression2` ; if so, the operator returns `true`. If `expression1` is greater than or equal to `expression2`, the operator returns `false.`
`<= (numeric less than or equal to)`	Compares two expressions and determines whether `expression1` is less than or equal to `expression2`. If it is, the operator returns `true`; otherwise, it returns `false`.
`() (parentheses)`	Groups one or more parameters, performs sequential evaluation of expressions, or surrounds one or more parameters and passes them as parameters to a function outside the parentheses.
`" " (string delimiter)`	When used before and after a sequence of zero or more characters, quotation marks indicate that the characters have a literal value and are considered a `string`; they are not a variable, numeric value, or other ActionScript element.
`eq (string equality)`	Compares two expressions for equality and returns `true` if the string representation of `expression1` is equal to the string representation of `expression2`; otherwise, the operation returns `false`.
`gt (string greater than)`	Compares the string representation of `expression1` to the string representation of `expression2` and returns `true` if `expression1` is greater than `expression2`; otherwise, it returns `false`.
`ge (string greater than or equal to)`	Compares the string representation of `expression1` to the string representation of `expression2` and returns a `true` value if `expression1` is greater than or equal to `expression2`; otherwise, it returns `false`.
`ne (string inequality)`	Compares the string representations of `expression1` to `expression2` and returns `true` if `expression1` is not equal to `expression2`; otherwise, it returns `false`.
`lt (string less than)`	Compares the string representation of `expression1` to the string representation of `expression2` and returns a `true` value if `expression1` is less than `expression2`; otherwise, it returns `false`.
`le (string less than or equal to)`	Compares the string representation of `expression1` to the string representation of `expression2` and returns a `true` value if `expression1` is less than or equal to `expression2`; otherwise, it returns `false`.
`- (subtract)`	Used for negating or subtracting.
`-= (subtraction assignment)`	Assigns `expression1` the value of `expression1 - expression2.`
