You could easily draw a big smiley face or a panda or whatever you like! But not just BASIC. Other languages like: LOGO and Pascal were right there on many computers.In this century, you may have dozens of programming languages lurking on your machine. But how to use them?? A fundamental secret! Well, no more. We cannot stand for that. Hackety Hack will not stand to have you in the dark!!
