  Many personal computers are based on one of the 86 series of Intel microprocessors, namely the 8086, 80286, 80386, 80486 in order of increasing power. Programming the computer in the relevant assembley language allows the user to take full advantage of the speed and power of the microprocessor. This book is written for PC users who already have some familiarity with a high level language such as Basic, C, or Pascal and who want the extra facilities and efficiency of assembley language. The book starts at an elementary level with the basics of assembley programming and the properties of the microprocessor in its simplest mode of operation, the real address mode. Instructions for this mode of the 8086 and 80286 are progressively introduced through illustrative programmes and subroutines. Further topics discussed are operating system calls and the 80286 protected mode. A separate chapter deals with the additional instructions of the 80386 and its modes of operation. Expanded and extended memory are also covered. The 80x87 coprocessors are treated for the benefit of readers who have one either as a part of the 80486 or as a complement to their 80 x 86. Numerous exercises are provided throughout the text. These enable the reader to test how well his or her understanding is going and to gain the experience in assembley programming which will give the reader the practice and confidence to undertake the programming of his or her own applications.
