automatically
closed. This is called
"unlistening"
and it
means
that in
order to PRINT#
more data, you must
re-open the file by
using
another
CMD
command. By
the way, please
notice
that you can
NOT
leave
a space
between
PRINT and #
or the command
will not
work.
NOTE: In CBM
BASIC
V2, the
PRINT command can
be
abbreviated by using
a
"?".
You
can NOT
do this
with
PRINT*.
You
must
always type
PRINT#
in full.
The
SYNTAX
for the
PRINT* Command is:
PRINT*
Ifn,
data
PRINT*
99,
"HELLO
VIC"
PRINT*
2,
CHR$(124),123,63,76
The CLOSE Command
The
CLOSE
command is a very important command to
use efficiently. You
should always CLOSE
a
file
after you've printed from it. The reason
is
that you can only
have
a
maximum
of 10 files open at
anytime.
Therefore,
if you
make a habit of closing
files when
you've finished
with
them, you
will always have the maximum
number of
files available.
NOTE:
Since the
CMD
command
does not
close the line
to
the
printer,
you
must
always follow
a PRINT*
command
with
the
CLOSE
command
in order
to properly
close a file.
The SYNTAX for the CLOSE Command is:
CLOSE Ifn
CLOSE
99
