The Freeze Output Ids utility performs the Check Model function and locks all MDL
        output IDs to their respective values resulting from Check Model.
        This ensures that any post-processing step that is
            dependent on an output ID is not affected if the MDL model gets additional output IDs
            added to it. Each output ID has a corresponding *SetEntityID() statement in the
            resulting MDL model. Select Freeze Output Ids from the Tools menu to activate the
            utility.
