Hello World
In my younger days, which almost seem like a lifetime ago now, when people were learning a programming language, the first program they wrote was usually a very simple one which merely printed out the message "Hello World!". I don't know if this practice is continued today, since I haven't programmed in anger for a lot longer than 20 years, but for my first serious and determined attempt at this website, I thought it would be a good thing to do the same! So, here we are! Hello World!
