Section 4
Storing and Recalling Numbers
You have learned about the calculating powerthat exists in the four-
register automatic memory stack and the LAST X register of your
HP-67 calculator. In addition to the automatic storage of intermediate
results that is provide by the stack, however, the HP-67 also contains
26 addressable data storage registers that are unaffected by operations
within the stack. These registers allow you to manually store and
recall constants or to set aside numbers for use in later calculations.
Like all functions, you can use these storage registers either from
the keyboard or as part of a program.
Storage Registers
The diagram below shows the addressable storage registers. You can
see that these registers consist of two banks, the primary registers
and the secondary registers. The subscripts A through E and 0 through
9 refer to the register addresses.
