6502 BASIC removing a character

How do I delete a character in 6502 basic? Like reverse print... Would there be a way to channel the del key code into a program? I have tried looking at the reference but there is nothing there for a command.

Solution

  • As OldBoyCoder suggests, it can be done - but the character depends on the platform.

    10 PRINT "AB";
20 PRINT "C"

    Output on Commodore PET or Apple II:

    ABC

    For Commodore PET add:

    15 PRINT CHR$(20);

    Output:

    AC

    On the Apple II you'd need to use 8 instead of 20 because the I/O firmware is different.
