Richard Gomm, almost completely disabled from birth, uses a microcomputer to control equipment around his room, to write philosophy and poetry and to entertain himself. For him it's a lifeline. Ian McNaught-Davis begins a systematic look at how micros are used and at how to use them. Assisted by John Coll he looks at how a simple system can be expanded to do many different things and takes a trip inside the BBC's own microcomputer.

The language most personal microcomputers understand is called BASIC and although different makes of machine use different 'dialects' of the language, the fundamental principles are the same on almost all machines. Ian McNaught-Davis describes the three programming structures and then writes a simple program which could be used to help children practise their maths skills. Catherine Robins visits a school where young children are learning to program the computer in a simple way.

How do computers handle words and how do programmers handle long programs? Ian McNaught-Davis takes a look at 'string' handling, at word processing and at the techniques of good and bad programming, with the aid of Ian Trackman.

Most modern computers are capable of displaying graphics - in other words, pictures. Ian McNaught-Davis begins an exploration of what you can do with a modest personal micro, with the assistance of John Coll. Among other things, they show how to create a simple animated figure who jumps up and down on screen.

Keeping information so that you can search for it in any way you want is one of the most important things you can use a micro for. But the information could equally well be from a large database and reached by using an ordinary telephone line. Ian McNaught-Davis looks at the fundamental principles behind the idea of a data base and begins his explanation in the BBC's gramophone record library, among , among 1,000,000 records.

Many small businesses - from the one-man band upwards - can benefit from the use of a microcomputer, but often people don't know what the micro can do for them and don't know where to go for advice. Ian McNaught-Davis explains the use of the micro in business with the aid of two consultants, Colin Harris and Ian Trackman.

Most modern personal computers can produce sounds of some kind - including music and speech. Ian McNaught-Davis and musician David Ellis investigate the making of simple and more sophisticated sounds, and they examine the elements of a music editor - the musical equivalent of a word processor. The programme also begins to look at languages other than BASIC.

How can the computer be made to sense what is going on round it and control motors or switches so that it seems to be doing something intelligent? Ian McNaught-Davis and John Coll look at a range of micro-controlled applications, from a sophisticated mechanical hand for the disabled to a number of do-it-yourself devices, including a temperature sensor and an inexpensive robot vehicle.

Almost nightly on our TV screens, in programme titles and credits, we see sophisticated computer graphics, including animations. With the help of Ian Trackman, a professional software writer, Ian McNaught-Davis investigates the extent to which the personal microcomputer can achieve these effects.

Someone, somewhere ... might have a message for you or some information you might want, or some computer software you could use. Getting 'Telesoftware' could involve using the telephone line or your television aerial. Ian McNaught-Davis and John Coll look at the use of the micro in communications. If you have got a BBC microcomputer, have a cassette tape-recorder with a microphone ready to receive an end-of-series message.
