(For
a
description
of the
PRINT
format
for
priming
Oil
the
computer
screen,
see
the
"[nput·Output
Statements"
section.)
This
form
of
the
PRINT
statement
allows
you
to
write
d;:l.la
onto
an
accessory device.
The
PRIN
T
statement
can
be
used
to write only
on files
opened
in
OUTPUT,
UPDATE.
or
APPEND
mode.
The
hie-number
must
be
the
hie-number
of
a
currently
open
file.
When
the
computer
performs a
PRINT
statement,
it
stores
the
data
in
a
temporary
storage
area
called
an
input/output
(I/O) buffer. A
separate
buffer is provided for
each
open
file-number.
If
the
PRINT
statement
does
not
end with a
print-separator
(comma. semicolon.
or colon). the
record
is immediately
written
onto
the
file
from the
I/O
buffer.
If
the
PRINT
statement
ends with a print-separator, the
data
is held in the buffer and a "pending" print condition occurs (see
"Using
Pending
Prints" in this section.)
The
information you need for
creating
a print-list to record
data
on
accessory file
storage
devices is
discussed
here.
The
print-list
needed to display print lines (on a printer. etc.) is the
same
as
the
print-list
described
in "Input-Output Statements."
You
may
use
either
DISPLAY
or
INTERNAL
format for
data
stored
on
accessory devices. However. since these files
are
read
only
by
the
computer, by far the easiest-to'use and
most
efficient data-type
is
INTERNAL.
Using PRINT with INTERNAL-type Data
The
print·list consists of numeric and
string
expressions
separated
by
commas.
colons.
or
semicolons.
All
print-separators
in a print-
li:;t
have
the
same
effect
for
INTERN
AL
type
data
they
only
separate
the items from each
other
and
do
not
indicate spacing
character
positions in a record.
