Glad to see that you are enjoying the process. Remember, understanding patterns is the most important thing when learning programming. Those patterns are found in almost all programming languages. Getting a good grasp of them now will help you pick up any language very fast.
Thanks, I'm not entirely new to the discipline, but I've let it go rusty over the years and it's a case of digging out old knowledge and putting a new spin on it. I did get a good training in programming principles and you're right, it's served me well.
