NOTE
Unlike storage register arithmetic, the accumulation operation allows over-
flows (i.e., number whose magnitudes are greater than 9.99999999 x 10 99)
in storage registers R.0 through R.5 without indicating Error 1 in the display.
(c). To use any of the accumulations,
recall contents of desired storage register
into displayed X-register by pressing ~
q
followed by the number of the regis-
ter.
If this is done immediately after pressing D or ~- , the accumulation recal-
led is written over the number of data pair entries (n) in the display. To use both
~xand ~y
, press I@ El .
This simultaneously copies ~x from R.1 into
displayed X-register and copies
S
y from R.3 into Y-register. If this is done
immediately after pressing + ,x- , ~
or =
, the number in the Y-
register is first lifted into the Z-register.
Otherwise, the numbers in the X- and
Y-registers are f rst lifted into Z- and T- registers, respectively.
