Coding For OrderCheck()

 
I have used 'How To Write An Expert Adviser' to create my own Expert Adviser. A recent MT5 update has caused some warnings because I believe I have OrderSend() without OrderCheck(). Does anyone know how to code the OrderCheck() function? The documentation provided is not sufficiently clear to work out the coding.
