Naming a Formula

formulas
helps
you
identify
them
later. Figure

shows
a
formula
list
containing
two
named
formulas
and
one
unnamed
for-
mula
.
The

precedes
the
formula; a colon
separates
the
name
from
the
beginning
of
the
formula
.

Formula names
To
name
a formula,
type
in
the
name
before you
type
in
the
formula.
Separate
the
name
from
the
formula
with
a colon ( :
).
For example, to
enter
the
formula
PRICE = INVOICE x DISCOUNT,
and
name
it
DISCTPRICE, type:
DISCTPRICE : PRICE 0 INVOICE 0 DISCOUNT.
If
you
type
in
a
formula
without
a
name,
you
can
add
a
name
later
using
the
...
key
.
Names
can
be
any
length
and
can
include
any
characters except
+,
-,
x,
-;-,
),
(,
<, >,
"',
:,

and
space.

two
or
more
formulas
contain
the
same
user
-variable,

appears.

two
