Hello,
the public keyword marks the scope of the variable to the public scope in
whatever class it's in. There is no "global" keyword, as far as I know. I
recommend using a class (You have to anyway for the main function I believe),
or passing the variable as an argument to the functions that need it, either
byref or byval.
