A86: More (sqrt) KEY questions

There is still an error, even with the -2 part. It works best when you
remove it all together,
I think it is because you cant have two .org addresses starting at $D748,
how would it know where to jump?

Why do you have to define a token at all? What is a token? Why is is there?
So you
copy the token and the rest of the program 2 bytes after the ABS address of
the newly
created program. What is this 2 bytes you need to skip on the newly created
program? The size? Why do you need a token at all? I tried to remove it but
yes, it crashed with an error 10 data type.
Does anyone know what the format of a PROGRAM file?
Another thing I cant seem to figure out. What are the equates for the
keypresses?? I checked all the.INC files but they are completely different,
even for the geykey, getky, and any function around. I cant figure it out..
How do you know what keypress is which? Like on Yugi2 $09 was the equate for
the enter key. How did you know this (not in the .inc files) and what are
the other key equates?
Thanks,
BTW I got the program working. I have it now so it wont let you press the
enter key. But I really need to know the other keys. I think it would be
cool if I wrote a program that turned the PGRM button into a CUSTOM button,
that way I can make it so my friends cant access my games, and then have
another key like the colon key fix it so you can access the program menu
again.
Thanks for you help Dux,
