Script, Scripting Language, VBScript elements, Server-Side VBScript Operator Assignment

VBScript Assingment Operator

The assignment operator is = Operator

= Operator

last updated 11/17/2017

Comparing equal to operator is used to create a value by comparing that the first and second expressions are equal to each other. While assigning equal to operation is used to assign a value to variable1 copied the second expressions.

Syntax

expression1=expression2
variable1=expression2

Argument

expression1Any expression.expression2Any expression.variable1 Any variable or any writable property.

Remarks

  • The expression returns True if both expression1 and expression2 are equal to each other.
  • The expression returns False if both expression1 and expression2 are not equal to each other.
  • The expression returns Null if either expression1 or expression2 is Null.
  • If both expressions are numeric then perform a numeric comparison.
  • If both expressions are strings then perform a string comparison.
  • If one expression is numeric and the other is a string then the numeric expression is less than the string expression.
  • If one expression is Empty and the other is numeric then the Empty expression is evaluated as 0 to perform a numeric comparison.
  • If one expression is Empty and the other is a string then the Empty expression is evaluated as zero-length string, "" to perform a string comparison.
  • If both expressions are Empty, then two expressions are equal.
  • The name on the left side of the equal sign can be a simple scalar variable or an element of an array. Properties on the left side of the equal sign can only be those properties that are writable at run time.
