Now, this guy above had Atic Atac, Nodes of Yesod, Exolon, Heavy on the magick... and one day one of the babies made me start thinking "How the hell do all these stuff work?". I was keen to know! Digged deep, figured out and now I'm here.
If you never wrote this code or similar:
10 PRINT MARK IS CLEVER
20 GOTO 10
You never was a programmer and will never be. Trust me on this ;)
