goto Statement

The goto statement redirects execution to a specific point in a function.

Syntax

goto label;

Usage

You can jump to any location within a function by using the goto statement. To do so, you must create a label—an identifier followed by a colon—at the point at which execution should continue. As a rule, goto statements should be used sparingly because they make it difficult to track program flow.

Example

The following example uses a label to loop continuously until a number greater than 0 is entered:

function clickme_Click ()
{
restart:
   var number = 10;
   if (number <= 0 )
      goto restart;
   var factorial = 1;
   for ( var x = number; x >= 2; x-- )
      factorial = (factorial * x);
   TheApplication().RaiseErrorText( "The factorial of " +
      number + " is " + factorial + "." );
}
