    * Learn to use comment cards (yes I am that old ;), while it may seem pointless with simple programs it will be of great value in the future (in particular to those looking at your code).
    * What happens if the user inputs 5 for N ? You need some error trapping, (i.e. you need to tell them they goofed since N must be between 10 and 100000 and re-request the value of N).
    * Is there really a need for a vector (M) and 2 do loops in this program ?
    * Since you have declared "Implicit none" how does the compiler to know
    (i.e. how do you tell it) that random is a REAL function ?
