FLASH® LITE™ 2.x - Adobe Help and Support

Operator Description
" (string delimiter) When used before and after characters, quotation marks (") indicate
that the characters have a literal value and are considered a string, not
a variable, numerical value, or other ActionScript element.
- (subtraction) Used for negating or subtracting.
-= (subtraction
assignment)
+ addition operator
expression1 + expression2
Adds numeric expressions or concatenates (combines) strings. If one expression is a string, all
other expressions are converted to strings and concatenated. If both expressions are integers,
the sum is an integer; if either or both expressions are floating-point numbers, the sum is a
floating-point number.
Note: Flash Lite 2.0 supports the addition (+) operator for adding numeric expressions and
concatenating strings. Flash Lite 1.x only supports the addition (+) operator for adding
numeric expressions (such as var1 = 1 + 2 // output: 3). For Flash Lite 1.x, you must
use the add operator to concatenate strings.
Operands
expression1 - A number or string.
expression2 - A number or string.
Returns
Object - A string, integer, or floating-point number.
Example
Usage 1: The following example concatenates two strings and displays the result in the
Output panel.
110 ActionScript language elements
Assigns expression1 the value of expression1 - expression2.
: (type) Used for strict data typing; this operator specifies the variable type,
function return type, or function parameter type.
typeof The typeof operator evaluate the expression and returns a string
specifying whether the expression is a String, MovieClip, Object,
Function, Number, or Boolean value.
void The void operator evaluates an expression and then discards its
value, returning undefined.
