is scanning the
keyboard (BASIC'S

not work during
cassette,
printer or

When you want to copy the
Display

will stop what it's
doing and
print the screen.
The Computer
will print the
entire display,
blanks and all.
If
you
are only interested
in printing the top
portion of the display,
press (BREAK)
when those
lines have been
printed.
If a printer is not
available, the Computer
will wait
until it becomes
available or
until
you
press (BREAK) .
If the Display
contains special characters
or graphics
characters, they
will
be
displayed as periods.
Note:
You can also
activate the
Print-Screen
function via the BASIC USR
function.
