The
line PRINT
«l

"PEN" i
"PAPER"
(in your
disk
program)
would print
this in your
disk
file:
PENPAPER*
The
Computer
would
read PEN
5
(with
all
the blank
spaces)
back into
memory
as
one
item.
(Reason;
although the
Computer
nor-
mally
interprets
blank
spaces
as
a delimeter, it
will
not
interpret
them
in this way
when they
follow a
string
and precede
a number).

AN
ATTRACTIVE
DISK
FILE
The
Computer would
read
PENPAPER
back
into
memory
as one item.
(Reason: there
is not a
"deli-
meter"
—
a comma,
quotation mark,
or
space
—
to
separate
PEN
from
PAPER).
The line PRINT
*l
,
"JONES >
MARY"
would
print
this in
your
disk file:

JONES
t
MARY*
The
Computer
would
read
JONES,
MARY
back
as two
items:
JONES and
MARY.
(Reason:
The
Computer
interprets
the comma
as a
delimeter).
The line PRINT «i

"PEN" , 5,

print
this
in your disk file:
