If you've played with DR Logo (found on one side of your CPM system disk), you'll have no trouble getting to grips with this program from Derek Johnston of Belfast. It's a cutdown version ol Logo It works from the Amstrad's native operating system and according to Derek is anything up to 20 times faster BarLogo gives you five new commands from Basic. - |FD , x is equivalent to DR Logo's FD command. The variable x is the distance you wish to move the graphics cursor or turtle forward. For example |FD,40 moves the turtle by 40 pixels
- |BK , x moves the turtle in the opposite direction to which it is facing : |BK , 32 will move the turtle back 32 pixels
- |RT , x will move the turtle to the right by x pixels.
- |LT , x moves the turtle left.
- |SH , x turns the turtle through x degrees. For example, |SH, 90 moves it by 90 degrees.
By mixing Bar Logo and Basic, complex designs can be produced. In fact, anything that can be done from DR Logo can be done equally well (but faster) using Bar Logo and Basic The lust listing pokes machine-code into memory and then saves a binary file to cassette or disk. To use Bar Logo in your own programs, you must incorporate the following line in your listing: 10 MEMORY &A411: LOAD"barlogo.bin", &A412: CALL &A432This loads Bar Logo into memory and lets you make use of its commands.If you're stuck for ideas try running Derek's demo program. It's impressive AA#25 ★ AMSTRAD CPC ★ DOWNLOAD ★ |

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. |
