In the last chapter, we looked at how easy it was to extend SuperBasic with new procedures and functions. Hopefully you all tried out the exercise I left for you to do, if not, there will be points deducted from your final score at the end of the course!
In this chapter, we shall take a look at the QL's screen memory and how to play around with it. I won't be writing any extensions to SuperBasic this time, but you could extend some of the routines to do so yourselves, and extend SuperBasic to your heart's content.
