BASIC REGISTERS
r..l
-100
Series
Calculators contain three
bas-
-
,.::ds
of
registers: a
work
register (display
.:-.:oiv),
two
adders
(left
and right),
and
the
::',ict
or log
register. The basic keyboard
is
::rrised of the
black adder keys, the
blue
,.
;:gister keys,
and
the white numeral keys.
.
:istinctive feature of the
Wang calculating
logic is the
ability to
generate logarithms and
exponentials. This
ability
is most readily
seen
in
the
ex and
los x
kevs. While the
use
ol
lhis
type of logic
adds
considerable basic power
to
the calculator,
the explanations in this section
do
not
consider the arithmetic operation
from
the point
of
view
of
logarithms. Multiplica-
tion,
division, squaring, and extracting
square
roots are
all
considered
as
normal
algebraic
calculations.

KEYBOARD ARRANGEMENTS
Table 3-1 lists the keys
associated
with
the
various models in the
300
Series
calculator line.
Operating examples start
with
the keys that
are
common to
all
models and progress
through
the
series
to the
explanations
of the
keys
pe-
culiar
to
the more sophisticated models.
Each
sample problem has been
carefully
chosen
to
allow a fuller understanding
of the
calculator
operations. Users
that
require additional in-
formation for
special
applications
are
uiged to
contact
their local
Wang Representative
for
assistance.
The
"Code"
columns
following
the
various keystroke commands are listed
for
fa-
miliarity
and
are associated
with
the card pro-
gramming capability discussed
in
Section
4.
