Sorry, you hit a bit of a hot button. I teach programming and I have been a
programmer for 35 years. I can't tell you the number of times I have seen
programmers, including myself, tie them selves up in knots trying to avoid
doing something twice in piece of code. It seems to be an instinct in people
who become programmers to want to avoid doing anything twice.

No issue at all.

So, copy and store the data, and Init and Quit SDL as needed.


Yep.

Thanks for the reply!  I think I got what I needed.


I'm glad to be of help.
