One of the first things that becomcs apparent to anyone who becomes involved in computing is the problem of software compatibility. There are a multitude of different computers, each requiring their own version of a program before they can load and run it properly. There have been attempts to overcome this problem, and CP/M is one of the most successful of these. There arc almost countless computers that are capable of running under the CP/M operating system, and the CP/M system effectively irons out differences between computers so that they can run the same software (provided it is designed to operate with a CP/M system of course). The success of CP/M has been such that there arc now thousands of programs available which run under this system. CP/M is more than just a program to give a common set of standards, and hence software compatibility between various machines. It includes a range of commands that help with such things as file copying, file editing, and directing data output to the appropriate device. In order to use and run applications programs running under CP/M it is not essential to have even a basic understanding of this system, but a reasonable knowledge of the subject can certainly be of immense help when minor problems occur, and also helps the user to fully exploit the potential of the system. This book gives details of the CP/M commands, and it does not assume a great deal of technical knowledge on the part of the reader. It does assume that the reader has access to a computer which will operate under CP/M, so that some simple instructions which help to demonstrate the way in which commands operate can be entered and run. It is not absolutely essential to try out the example instructions, but doing so greatly adds familiarisation with CP/M commands and makes it much easier to gain a proper understanding of the way in which they function.

Page créée en 461 millisecondes et consultée 759 foisL'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko. |
