SQ23: This superb program by Dutch programming team Dragonbreed Wetware squeezes 17k screen files down to a more manageable size. The most popular squeezer in the public domain, it was used to produce slideshows such as Amiga Graphics (which is how 49 pictures were crammed on to one 3-inch disk). Run the program, and when you're prompted by “File:”, enter the filename of the screen you want to squeeze. (If you're using a cassette-based system, make sure to add an exclamation mark at the start to avoid untidy prompt messages appearing). The next question is ''Include Loader Y/N:”, to which you should press Y. After this, ''Exclude Types (ABC):” will appear. Usually you simply press ENTER in answer, but if you want to exclude the wipe-effect squeeze then enter C and press ENTER: or, if you want to force this effect, type AB and press ENTER. After this, the screen will load and will be squeezed. You will then get to to name the saving filename (disk users can simply press ENTER, and the original file will be replaced with the squeezed version), and the file will be saved. Finally, to the all-important question: how do you reload squeezed files? Easy. All you need to do is load them anywhere into memory, and CALL the address where they've been loaded (the code is relocatable). This means that you can load as many files into memory as will fit. For example, say you have two MODE 2 squeezed files, “SCREEN1.BIN” (length &FF0) and “SCREEN2.BIN”, and you want to flip between the two: 10 MEMORY &3FFF
20 LOAD "SCREEN1.BIN" ,&4000
30 LOAD "SCREEN2.BIN",&4000+&FF0
40 '
50 MODE 1
60 CALL &4000: CALL &BB18
70 CALL &4000+&FF0: CALL &BB18
80 GOTO 60USQ2: An easy way to unsqueeze screens squeezed with the above program. Simply enter the filename (remembering the exclamation mark if you're on tape) and the screens will be restored to a standard binary file.AA

Page créée en 473 millisecondes et consultée 598 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. |
