N ow everything
that
the VIC would normally display on the screen will
be printed on the printer including the READY message, the display, and
error messages. Your entries will still be displayed on the screen. To
see
this,
try performing some
PRINT
statements.
EXITING
THE
CMD
MODE
There are three ways to exit the
CMD
mode.
1.
Press
RUN/STOP
and RESTORE
at
the same time. This will reset the
entire system and restore the computer to its default condition.
2.
Redirect the
CMD
instruction to another device, such as the video
screen, device #3.
CMD
3
3.
Enter a
PRINT#
instruction
to
the primary device.
For
example, if
you had made the primary device
#1
with
CMD
1,
you would exit
this mode with
PRINTtU
Of the three methods, the
last-using
a
PRINT#
instruction-is
pre-
ferred because it will exit the
CMD
mode and also empty the printer buffer.
Characters may have been left there from
an
incomplete
PRINT
statement
(one
that
was terminated with a semicolon).
