(excerpt from the main body of the text:)

Now the principles of windows have been mastered, you should be able to use them to good effect in your programs. One example is shown in fig.2. It is a simple maths test program for primary school children, allowing them to practise any multiplication table of their choice. The screen display is split into windows, each window having a specific purpose, so that the child should quickly know where to look for any part of the operation. The main window, on the left of the screen, provides the questions, the smaller yellow window on the right hand side provides the response (correct or wrong, or the complete multiplication table, if the child has real problems in getting the answer). The blue window at the bottom of the screen is used for input of answers.

You will notice when running the program that the main window has a 'shadow' to it. This is a popular effect in many QL business programs; it gives the impression that a window is 'standing out' from the rest of the screen, so highlighting to the user which window should be looked at most closely.

If you're not very familiar with SuperBASIC, there may be several constructions within the mathematics program which are confusing. Don't worry, because in the next five issues of ZX Computing most of the QL's special BASIC commands will be featured.
