Can you clarify? quotation mark, home, quotation mark will write an inverted S between two quotation marks. By moving the cursor and using space to erase the left quotation mark, and moving the cursor again to the right of the inverted S, and typing shift+Y and any reasonable address to jump to, and then return, it will execute a SYS. (It of course requires some machine code to execute, my idea here is to use screen ram as that seems to be the only way we could enter data in memory using the joystick ports. It will of course be a challenge to write some useful machine code with only the the instructions available using the chars that we can type). -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
