Curious title, but this looks like a good and meaty book for the more experienced and adventurous programmer. And there's a large variety of programs to type in and digest, most of them of the practical kind.
The book is structured into chapters dealing with time, graphics, drawing, filing and word processing, and finally with accounting. Each chapter contains a set of programs chopped up into 'modules' which are listed and discussed separately, and explained almost line-by-line - so there's no excuse for not knowing what's going on.
The final chapters look at more substantial programs; like Unifile, a filing program and Texted, a simple wordprocessor written in Basic. Towards the end, you're confronted with two finance programs called Banker and Accountant. If you can muster up the enthusiasm to key them in, they'll probably give you a good grounding in business computing.
