That's one solution but its not a very good one.

Global variables are not considered good practice for many
reasons. In particular, they make code reuse difficult and
if you ever need to use your code in a multi-threaded
environment, to improve performance say, they are nearly
impossible to work with.

It's much better to pass the required value out of the function
as a return value.

No inconvenience, its what the list is here for! :-)
