Variables

Top  Previous  Next

Variables start with a single dollar-sign ($) followed by the variable name. The name can contain characters (a-z), numbers (0-9) and the underscore character (_). The length of a variable name is not limited. Variable names are case insensitive ($abc is the same as $ABC). You can assign numbers and strings to a variable, strings must be enclosed in double quotation marks ("..."). An explicit declaration is not required.

 

You can assign the following values to a variable:

 

Number
String - enclosed in double quotation marks ("...")
Another variable
Result of a built-in function

 

Examples:

$i = 1
$string = "This is a string"
$s = $string
$result = GetQuestionBoxResult

Numeric operations

For numeric calculations you can use the following operations:

 

variable = Operand1 + Operand2
variable = Operand1 - Operand2
variable = Operand1 * Operand2
variable = Operand1 / Operand2

 

Operand1 and Operand2 can be numbers, other variables or the result of a built-in function.

String operations

For strings you can use the following operation:

 

variable = Operand1 + Operand2

 

Operand1 and Operand2 can be strings, other variables or the result of a built-in function.

 

Examples:

$i = 1
$i2 = $i + 10
$s = "Text1"
$s2 = "Text2"
$s3 = $s1 + $s2

 

Please note that maximal one operation is possible per line.

Variables in MessageBox and other commands

Variables can also be used in the MessageBox command and in parameters of all other commands. If you place the variable name between { and }, then it will automatically be replaced with the value of the variable.

 

Examples:

$i = 1
$s = "Text1"
MessageBox "Value of i is {$i} and value of s is {$s}"
 
$dynamic_filename = GetUniqueID + ".htm"
CreateReport /template="{bookmarkdir}changes.htm" (+)
             /output="e:\{$dynamic_filename}" (+)
             /bookmarks=changed
