Apple POKEs
On the Apple, POKE 1011,0 re-boots on your disk when CTRL-RESET is pushed. This can be very inconvenient later on when you are in the middle of a program. Is there another POKE statement to get out of that?

If a value of 157 is POKEd into location 1011, this feature will be disabled. This was determined by PEEKing the above location after powering up the Apple. PEEKing a particular location before and after a program is RUN would work on all computers which allow PEEKing and POKEing. This is a useful way to determine the default (normal) status of important addresses.
