A household utility for the Amstrad machines -written by Alan Lawless Ever since purchasing my Amstrad I have been under pressure to justify the expense and make it do something useful! It has often been the case in our household to find food well past its best down in the darkest corner of the freezer and subsequently have to be thrown away. So it was that I decided to search for a way of monitoring the contents of the freezer and learn how to drive my new acquisition!

The program is menu driven and gives the user the ability to add and delete items, view a list of contents in alphabetical order, and save the information on tape under the file name "Freezer.dat". As the user is prompted to enter the date on power up, a facility has been added to warn whether or not any item is past its best or whether anything in the freezer should be eaten within the next "x" weeks.

L'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.
