This book was originally published in China in 1995. This is the first English edition. This book is a complete text book on QBASIC programming. It assumes that the reader knows very little and builds up to quite an advanced level. It contains some obsolete material, such as MS-DOS. This was intentional, as it is intended to match the original Chinese edition. QBASIC still continues to be used. Nowadays if people want QBASIC to run on their computer, they need to download QB64. The latest version of this was released on 21st August 2009. QBASIC, or QB64 as it is now called, is a very good choice for a first programming language, as you can achieve a lot with very little effort.
