Syntax

@if (condition1)
      statement1
    @elif (condition2)
      statement2
    @else
      statement3
    @end

The @if statement operates much like a typical if conditional statement.

The @if statement evaluates compiled variables and has a slightly different syntax.

The @elif statement operates the same as the JavaScript else... if statement

Only one @else statement should be used to catch conditions that don't meet any of the previous conditionals.

Like the @elif statement, the @else statement is optional.

The @end statement is required at the end of all if conditionals.

<html>  
    <script language="JScript">

      alert("You are using a DEC Alpha processor.");
    @elif(@_mc680x0)
      alert("You are using a Motorola 680x0 processor.");
    @elif(@_PowerPC)
      alert("You are using a Motorola PowerPC processor.");
    @elif(@_x86)
      alert("You are using an Intel processor.");
    @else
      alert("I don't know what type of processor you have!");
    @end
    -->
