Function to Close all orders where Magic Number = 0

I need the FOR/LOOP portion only  that will iterate through all  OPEN and PENDING (buy and sell) orders that automatically close any of these orders where the MagicNumber = 0.

I'll be integrating this into some other scripts that I already have so I only need this Loop functionality and nothing else.  You can build it as a Void function.

Pretty basic and simple.

thank you
