For the first time ever in a calculator, your WP 34S offers a
choice of 4 or 8 stack levels. So either T or D will be the top level.
Registers A - D will be allocated as stack registers if required.
Please see below for top level repetition and stack contents in
complex calculations. While register L takes the real part of the
last argument, I takes the imaginary part when a complex func-
tion was executed (see
C
LASTx).
Using , registers R86 - R99 will contain statistical sums as
indicated. J and K may be taken for parameters of statistical dis-
tributions.
Unless required for the purposes just mentioned, A - D, I, J, and
K are available as additional general purpose registers. For indi-
rect addressing, the stack levels and named registers carry the
numbers as shown at right.
For information about the flags, please turn overleaf.
