Assigns a value to a variable. If this is its first use, the variable will be created and assigned the specified value. If the variable already exists, its value will be changed to the value specified.
Requires a variable name, followed by an equals sign (=), followed by a value. The value can be a string, an arithmetic expression, or a string expression.
{SET a = 5}
{SET b = 3}
{SET c = a + b + 4}
{SET h = "Hello"}
{SET w = "World"}
{! string expression }
{SET hw = {VAR h}{VAR w}}
{! Concatenation of a string and variable}
{SET mornin = "Good morning "{VAR w}} {! No space between closing quote and {VAR w} }
{VAR hw}<BR>
c = {VAR c} <BR>
{VAR mornin}
This example produces the following output:
Hello World c = 12 Good morning World
