On this page, you will find some small QBasic programs and functions that I have written. If you find something useful and want to incorporate it in your program, feel free to do so. No need to ask for permission. Just copy and use whatever you like.
I learned QBasic programming language when I was 12 years old. Later I learned C, x86 assembly, Perl, and JavaScript. Programming is one of my hobbies. Most people don't program in QBasic anymore, and I rarely do as well. But still, this is a nice language, and it's perfect for beginners.
