-__Footnotes__
+Up there you see the problem with Hello World; most Hello Worlds look exactly like the Python one. It's not really meant as a sample program. What you learn from creating a Hello World program is how to use the language tools: it's a first exercise in entering, compiling and running a program on a paticular system, and it might make you go find the documentation on the I/O library in some cases. [99 Bottles of Beer on the Wall | http://99-bottles-of-beer.ls-la.net/] is slightly better for demonstrating the look of a language, PPR:WardNumber a lot better.
