type LIST N<return>

where N is the line you want to edit and <return> is the return key
(or is it enter on a II?)

Press ESCAPE to go into edit mode.  Use the arrow keys to move the
cursor over the beginning number of the line you want to edit

LIST 10

10 PRIMT "HELLO"
^
|
you want the cursor on the 1 in 10.  It will flash on and off, between
the cursor and the 1.

Press ESCAPE to exit the edit mode.

move the cursor to the right using the right arrow key

10 PRIMT "HELLO"
      ^ 

get it over (IE, directly on top of, so it is flashing) the M in PRIMT

type the letter N on the keyboard to fix your error (replace the M
with an N)

use the right arrow to get to the end of the line (right after the
last quote)
press <RETURN> to enter your program changes into memorty.

It is very easy to use.  There also AppleSoft editors that are nice,
check for errors as you type, etc.

you might have to do a POKE 33,33 to change the way the text screen
works for escape mode editing.

HOME
poke 33,33

do your editing.

TEXT

this will make the text screen 33 characters wide so that escape mode
editing works on long lines.  TEXT puts the text screen back to normal
so your programs text output looks correct.
