As I mentioned, I'm retired. This could be something I piddle with maybe an hour or two a day, off and on, for years. Right now, I have only photography as a hobby.

Thank you for your help. I'm definitely "A". When I got my masters in CS, I took all of the language classes they had and even had them pull in someone from industry to teach what was essentially "Compilers 2". There are books on Pragprog.com where they introduce 7 new languages in each book... Great stuff!
