===== Functions =====

Functions are defined in your script as shown in this example:

<codedoc>
Function	IsItemASword( $itemNum )
{
	if ( $itemNum = 112 )		// Sword
	{
		return( 1 )
	}
	else if ( $itemNum = 113 )	// Sword 2	
        {
		return( 1 )
	}
	return( 0 )
}
</codedoc>

This example function would be called from another part of your script like this:
<codedoc>
  $isSword = IsItemASword( $gTaskItem1 )
</codedoc>

Functions can have any number of parameters, and always return a value.
