As stated elsewhere,
10 print "Hello!" 20 goto 10
Then just variations on that theme, lookup other functions etc.
We don't need schools to teach programming either. Anyone who is interested in it can learn it themselves easily.
My son just made his decisions for GCSE options. He decided against doing IT, because they just play around with spreadsheets. He's learning to code at home, by himself, writing games and apps for his phone. That's the way to do it IMHO...
At school, you're going to be in a class where 50% couldn't care less about programming, and the rest will just slow you down. Self teaching is much better.
