Me too! It's a challenge, but it's worth the effort. Honestly, many people doubted I could do something like this because of the limitations, but I'm doing it and I'm very happy with the results I've gotten so far. Tonight, I'll check where I can get some input to learn C/C++ language. I really appreciate all the input you all have given me so far. Once, I wrote an essay about education and knowledge and I was awarded a scholarship because of it. There, I reflected that knowledge in contrast with political power, money, and material or financial wealth, the more one shares knowledge, the more one grows. Besides, knowledge cannot be stolen or taken away from us. The other three can vanish in a secondI'm liking the thought and effort that's gone into this so far...
