Section 6: Memory and Storage 69
Store and Recall. Numbers are copied into and out of the Index
register using and [RCL](1], operating the same as the other
registers.
X Exchange I. Analogous to the [xXy] function, will
exchange the contents of the X-register and the Index register.
Storing and Recalling Numbers Indirectly
Storage registers can be accessed indirectly using the [(i)] function:
()], (RCL][(i)], or [xx(i)]. The absolute value of the number in R;
determines the storage register address.* (In Floating-Point
Decimal mode, only the integer part is used.) The table below
shows the correspondence between R; and storage register
addresses.
Indirect Addressing
If Ry Contains: L(i))] Will Address:
9 (916) Rg
15 (F16) Re
16 (1046) R.o
31 (1F6) R
32 (201¢) R32 (= Rao,4)
33 (2146) Raz (=R,
The [STO][(i)], ()], and functions are the only means to
access a storage register beyond the first 32 (beyond 0 through .F),
but they can be used for any register, as the table illustrates.
*The absolute value is computed using a 68-bit word size and the current complement
mode.
