This useful program adds 18 resident system extensions to Amstrad Basic. While many such programs add commands which are combinations of Basic commands, the RSXs in this program can be achieved only through machine code and are aimed mainly at those with disc drives. The commands given are all useful and include many standard functions like Format, Read and Write commands. They make use of certain routines in the CPC computer disc operating system while the rest of the commands are dedicated to using the second bank of memory on the 6128 model. The non-disc commands include such functions as SWAP, which can be used to swap the location of the screen RAM between its two possible addresses. It is very useful because it allows one to store a graphics screen in one location and a text screen holding instructions in another. Another command. COPYM. allows the user to copy one section of RAM to another. It is specially useful in animation for copying certain parts of a program. As all the commands used are RSXs. They must be preceded by the bar sign, generated by holding down the shift and @ keys together. Your Computer

Page créée en 293 millisecondes et consultée 1947 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. |
