line input
(or
lineinput
—
the
space
is
optional)
is
similar to input, except:
*
The Computer
will
not display
a
question
mark when
waiting
for
your
operator's input.
•
Each
line input
statement can assign a value
to just
one
variable.
8
Commas
and quotes your
operator can use
as part
of
the string input.
*
Leading
blanks
are
not ignored
—
they
become
part of variable.
•
The
only
way
to

is
to
press

.
line input
is
a convenient
way
to input
string
data without having
to
worry
about
accidental entry
of
delimiters
(commas,
quotation marks, colons,
etc.).
The
(ENTER)
key serves
as the
only
delimiter.
If
you want anyone
to
be
able
to
input information into
your program
without
special instructions,
use the
line
input
statement.
Some
situations require that
you
input
commas,
quotes and
leading blanks
as
part
of
the data,
line input
serves well
in
such
cases.
Examples
LINE INPUT
A*
Input a$ without displaying any prompt.
LINE INPUT "LAST NAME
>
FIRST NAME?
" SN$
Displays
a
prompt message
and
inputs
data.
Commas
will
not terminate the
input
string, as
they
would
in
an
input statement.
