    Week 1 Saving a high score

"highscore.txt" must exist in the path and contain something,
initially 0 in this case. To track the highscore See comments below.
Note that this erroneous code evolved due to me trying to understand how the file modes r, w, a worked.
There is a curiosity in that the several integers seem to be added right to left ie the basic faulty 'number' is 3000. I would expect it to be 0003. ! """
