would
assign values as follows:
A$ = PECOS
B$= TEXAS
"GOOD MELONS"
C$
=
null string
If a
comma
is
inserted in the data
image
before the
first
double
quote, c$
will
get the value,
good
melons.
These
are
very simple
examples
just to give
you an
idea of
how
input works.
However,
there are
many
other
ways
to input data
—
different terminators,
different target variable types,
etc.
Rather than taking a shotgun approach and
trying to
cover
them
all,
we'll give a
generalized description of
how
input
works and what
the
terminating characters
and
conditions
are,
and
then provide several examples.
When
basic encounters
a terminating
character,
it
scans
ahead
to
see
how many
more
terminating characters
it
can
include with the
first
terminator.
This ensures
that
basic
will
begin looking
for the
next data item
at
the correct place.
The
list
below
defines the various terminating
sets
input#
will
look
for.
It
will
always
try to take-in the largest set possible.
