 From this link:
https://www.codingunit.com/c-tutorial-functions-and-global-local-variables

"A global variable is a variable that is declared outside all functions. "

I think this is not standard practice to use global variables. Just like
it is not OK to use goto. I have been coding XBoard (a chess GUI) , it
has lot's of global variables. Unfortunately I added some more to it.
