When you create a new Type object with the <a href='NEW.htm'>NEW</a> command, it is automatically appended to the END of the collection. Using INSERT along with <a href='BEFORE.htm'>BEFORE</a> and <a href='AFTER.htm'>AFTER</a> (and electively <a href='FIRST.htm'>FIRST</a> and <a href='LAST.htm'>LAST</a>) to put the Type object exactly where you want it. Sounds confusing - and chances are likely you'll never need this ability. But its here if you need it.
