This program sets up the CPC464 as a simple to use editing typewriter system (a poor person's word processing system). It provides facilities to store and retrieve text to cassette or disk, cut and insert lines, re-type lines of text, and display on screen in the 'what you see is what you get' format.

It's user-friendly with menu prompts at the top of the screen. There's a panic feature that gets you out to the main menu without loss of data - simply press [ESC] twice, then the small [ENTER] key on the numeric keypad to return to the menu.

The program does not feature a full screen editor, but uses the same facilities as the BASIC line editor. Each line is numbered, and menu functions manipulate text by use of this index number.

Notes:

  1. Don't use double quote marks " when the document is to be stored onto tape or disc. The computer interprets these as delimiters, and will terminate the line at the first set of quote marks.
  2. When storing the file to disc, make sure that the filename chosen conforms to the AMSDOS & CP/M standard of up to eight permitted characters, plus a three character subscri pt: eg ABCDEFGH.DOC
  3. To clear a document that that has been printed or filed, press [ESC] twice and re-RUN the program. Press the smaller [ENTER] key if you want to return without wiping off the document memory.
  4. During text input, typing E on its own at the beginning of a line, then pressing [ENTER], will return you to the menu..

The program operates with all Centronics interface printers. If you are using an EPSON compatible printer with features such as paper out sensing, auto form feeds, you may wish to override these functions by inserting lines 322-326.

322 PRINT#4,"PRINTER IS NOT ON LINE":SOUND 1,200:PRINT#8,CHRS(13);:SOUND 129,0
324 PRINT#8,CHR$(27);CHR$(56);:REM DISABLE PAPER OUT ON EPSON
326 PRINT#8,CHR$(27);CHR$(79);:REM DISABLE FORM FEED ON EPSON

If you are using a green monitor, then....

60 MODE 2: BORDER 0:INK 0,0:INK 1,26:

PAPER 0:PEN 1:G0SUB 1370

....will produce the best display combination.

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.
