Name Tags
for Numbers in Columns
It
is
often useful
to
know what the
numbers
in
your
columns
stand
for: dollars,
acres,
miles, gallons, or
bush-
els,
for example. You
can label numbers
as
you like
-
the
column operators
will
ignore them.
"Section Numb€r43,"
"$5.95,"
and
"200
acres"
will
be treated as
if
they
were
*43." *5.95."
and
"200."
Any
of
the
following
characters can
be
used
in labels: A to
Z,
a
to
z, space,
7o, $,
#, +,
@,
[,
/,
>,
{
,
}
,
-,
\
comma, or
the special symbols
for lira,
degree,
paragraph,
section,
cents,
florin, pound, yen, or division.
If
you precede
a
number
in
a
column
with
!,
&, *, l,
),
?,
r,
l,
",',
or _, sum
and
sumdisplay
will
treat
this
number
as
a
zero. This
can be
helpful.
When
reconciling your check-
book,
put
the amounts
of all your
checks
in
a column.
Precede any outstanding checks
with
?.
The
sum
of all
your
checks should
match your
bank statement.
If
you precede
a
number
in
a
column
with (,
-,
or <, then
sum,
sumdisplay, average,
and
avg
will
interpret
it
as
a
negative
number. Thus -100, (100),
and
<100>
will
all
be
treated
as
negative
100.
When the label
comes
after
a
number
in
a
column
vou can
use
any character except
a
digit
or
a
period.
Relative Address
Relative addressing
allows you toperform
operations
with
numbers
in
tables, such as adding the
fifth
number
in
column I
to the second number in
column
3
and
displaying
the
result
in
column
4.
An address is the
position
of
a
table entry
. Relative
means
"relative
to
where
you
are
typing the expression." A
relative
address is
written
z
se(xy),
Ixy]
,or usedisplay(xy).
The
x
and
y
stand
for two
number values
which
specify the
column
and
row
of
the number
you
are using.
The
x value refers to the horizontal distance
in
tab stops
from the
expression
you
are
typing. A
positive x
value
means
to
the
right. A
negative
x value
means
to
the
left.
Thus
if-r
is
"3,"
the
number
to be used
is in the third
column
to
the
right.
