A
print#
statement
creates a disk
image
similar
to
what
a print
to
display
creates
on
the screen.
Remember
this,
and
you'll
be
able
to set
up your print'#
list
correctly for access
by one
or
more
input
statements.
print#
does not
compress
the data before writing
it
to disk;
it
writes
an
ascii-
coded image of
the data.
For example,
if
a
=
123.45
PRINT#1
>A
will
write a nine-byte character sequence onto
disk:
123,45
(INTER)
The
punctuation
in the
print
list is
very important.
Unquoted commas
and semi-
colons
have
the
same
effect as they
do
in
regular print
to
display statements.
For example,
if
a
=
2300
and B
=
1.303,
then
PRINT#1
»A»B
places the data
on
disk as
2300 1.303
(ENTER)
The
comma
between
a
and
b
in
the
print#
list
causes 10
extra
spaces
in
the
disk
file.
Generally
you
wouldn't want
to
use
up
disk space
this
way,
so
you
should use semi-colons
instead
of
commas.
PRINT*1
?A5B
writes the data
as:
2300
1,303
(ENTER)
print#
with
numeric
data
is
quite straightforward
—
just
remember
to
separate
the items with semi-colons.
print#
with
string data requires
more
care, primarily because
you have
to insert
delimiters so the data can be read
back
correctly. In
particular,
you must
separate
string
items with explicit delimiters
if
you want
to
input# them
as
distinct strings.
For example, suppose:
A*="J0HN
0,
DOE" and B$=" 100-0 1-001"
Then:
PRINT»1
t
a$;b$
would
produce
this
image
on
disk:
JOHN
Q.
DOE100-01-001
(1WTER)
which could
not
be input back
into
two
variables.
The
statement:
