THE KEYBOARD
The "BREAK" key is for aborting the
execution of a BASIC program. If you get
lost in a BASIC program and do not know
the way out, pressing the "BREAK" key will
break you out and return you to the BASIC
command level. This is a fairly drastic step
and may ca use some data to be lost.
The "ESC" key is often used by application
programs as means to ESCape out of
whatever you are doing, just like the
function of the "BREAK" key in a BASIC
program.
In some programs, it is al so u sed as a "l ead -
in" character for special multi-character
commands . For instance, pres si ng the "ESC"
key followed by the "I" key (abbreviated as
ESC I) in the BASIC command level ca uses
the cursor to move up one line on the screen.
The "RESET" key represents a very drastic
step . Pressing it while holding down the
"CTRL" key (abbreviated as CTRL-RESET)
ca uses t he computer to abort whatever it is
doing and restart all over again. This often
causes the program and data in memory to
be lost as well.
In some cases, the computer may get stuck
and stop running.
In this case, pressing "CTRL-RESET" is the
only way to bring you out of this situation.
The two-key sequence prevents you from
resetting the computer accidentally.
