VARIABLES
1.
What
is
a
variable?
A
variable
is
a
letter
(or
character
combination
which
represents
a
memory
location
in
which
information
can
be
stored
(this
information
often
is
called
data
and
can
be
a
number
or
series
of
characters).
In
this
Computer
variables
are
divided
into
fixed
memories
(26
pieces)
and
a
flexible
memory
(refer
to
"Calculations
Using
Memories"
on
page
15).
The
memories
store
not
only
numerical
values,
but
they
can
also
store
items
composed
of
characters
(such
as a
person's
name
or
item
name).
Numerical
variable
A
data
memory
is
called
a
numerical
variable
when
it's
storing
numerical
values,
and
is
labeled
as
A,
B,
C,
A(1)or
A(28).
Character
variable
A
data
memory
is
called
a string
or
character
variable
when
it's
storing
a sequence
of
characters,
including
letters,
blanks,
numbers,
special
symbols,
and
is labeled
as A$;
B$;
C$ or
A$(1)
(the
$
being
called
a
"string"
-
e.g.
"A-string",
etc.).
(One
data
memory
can
contain
a
maximum
of
seven
characters.)
