Assignment

Description

Assigns values to variables or object properties or object
references to object variables.

Syntax

Argument	Description
variablename	The name of the variable or object property to which you want to assign a value. Variablename can include dot notation to qualify the variable with one or more object names.
expression	An expression whose datatype is compatible with variablename.

Usage

Use assignment statements to assign values to variables. To
assign a value to a variable anywhere in a script, use the equal
sign (=). For example:

No multiple assignments

Since the equal sign is also a logical operator, you cannot
assign more than one variable in a single statement. For example,
the following statement does not assign the value 0 to A and B:

This statement first evaluates B=0 to true or FALSE and
then tries to assign this boolean value to A. When A is not a boolean
variable, this line produces an error when compiled.

Assigning array values

You can assign multiple array values with one statement, such
as:

You can also copy array contents. For example, this statement copies
the contents of Arr2 into array Arr1:

Operator shortcuts

The PowerScript shortcuts for assigning values to variables
in the following table have slight performance advantages over their equivalents.

Table 7-1: Shortcuts for assigning values

Assignment	Example	Equivalent to
++	i ++	i = i + 1
—	i —	i = i – 1
+=	i += 3	i = i + 3
-=	i -= 3	i = i -3
*=	i *= 3	i = i * 3
/=	i /= 3	i = i / 3
^=	i ^=3	i = i ^ 3

Unless you have prohibited the use of dashes in variable names,
you must leave a space before -- and -=. If
you do not, PowerScript reads the minus sign as part of a variable
name. For more information, see “Identifier names “.
