Notes

  • Tester: Once installed, load your own routine in memory and (with RST6 instructions wherever you think they will be useful), when you are ready to test your routine type |TEST,addr (referring to the start address of your code). Press Esc to return to Basic or enter to continue with your program.

To send parameters to your routine, include these before the address e.g. |TEST,A$,B$,&6000

  • Keywords: The type-in replaces Basic commands with abbreviations as follows:

After running the program, 464 users simply CALL &A200 to install the keywords 664 users type POKE &A201,&5B:CALL &A200 6128 users enter POKE &A201,&5E:CALL &A200

Two bar commands are introduced to switch on/off the keywords: |KWS.ON and |KWS.OFF

NB use |KWS.OFF before an INPUT command and |KWS.ON after The full stop in a keyword replaces a space, bracket and quote mark in many instances e.g. PRINT ch.45) and op.dummy" for example

  • One Line Entertainer: by changing the value of a$ you can program your own tunes; @ acts as a pause
  • Keysave: Once you have defined the function keys to your liking, run this routine. It will save a file called KEYS.BIN. Whenever you want to load the key definitions without destroying Basic or using up memory, enter LOAD"KEYS"
