Starting this month, we hove the beginnings of a database. We shall add a little more to it in each issue (I hope!), and gradually explain what we are actually typing in, so that we conperhaps learn a few things along the way. I don't pretend to be an expert programmer, and I've no doubt that parts of the program could ba improved, so if you have any suggestions or comments then please send them to me (John Packham), and if I think they do improve the program, then I shall put them in for all to see and use. For those of you who do not know what a Database Is, let me try to explain. In simple terms, it is a computerised card index system. Perhaps you have a record collection you wish to keep track of, or a list of Names & Addresses, or Recipes. In fact, anything that you have a whole list of could be put into a database for easier storing and retrieval. Take our record collection for instance... With an old fashioned card index system, each card- would have written on it things like Artist, Record Title, Record Label, Year of Release, etc. Each of these individual headings are what Is known as FIELDS. The whole completed card would be called a RECORD (this is nothing to do with the fact that we are dealing with a record collection. We could be dealing with recipes, and a whole card would still be colled a RECORD). Now, suppose you had 1000 of these cards. To pick out all the ones with the VIRGIN record label could take some time, but a computer could do It In a matter of seconds. Also, you may want to sort them into ascending order on the Year of Release. Again this would take time manually, but only seconds with a computer. You can begin to see the advantage of using a computer to keep track of your lists can't you. Now, ideally, a computer would allow you to have an unlimited number of FIELDS & RECORDS, but due to the memory limitations of the humble CPC, we have to keep the maximum number down. Anyway, on with the start. All this does is to display a title page, and a few main options.... the trickier stuff comes later! CPC USER | ★ AMSTRAD CPC ★ DOWNLOAD ★ |

CPCrulez[Content Management System] v8.732-desktop/c Page créée en 102 millisecondes et consultée 278 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. |
