NOTE
Unlike storage register arithmetic, the accumulation operation allows over
flows (i.e., number whose magnitudes are greater than 9.99999999 x 10 )
in storage registers R.O 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 B
H followed by the number of the regis-
ter.
If this is done immediately after pressing~ or ~- , the accumulation recal-
lfldxi~n~i;t;n over the number of data pair entries (n) in the display. To use both
press ~ ~ . This simultaneously copies ~x from R.1 into
displayed X-register and coies~y from R.3 into Y-
ister.

If this is done
immediately after pressin ddg Z+ , ~ , I@
, or ENTER I
, the number in the Y-
register is first lifted into the Z-register.
Otherwise, the numbers in the X- and
Y-registers are first lifted into Z- and T- registers, respectively.
