38 HP-67/HP-97 Compatibility
The correspondence between HP-67/HP-97 data storage registers and
HP-41C data storage registers is as follows:
HP-67/HP-97 HP-41C
Data Storage Registers Data Storage Registers
Primary Registers (10) Roo through Ry
Secondary Registers (10) R,, through R,
A R,
B R.,
C R2.
D R2s
E R24
| Ras
Note that primary HP-41C data storage registers are always identified by
a two-numberregister address, whereas HP-67/HP-97 register addresses
are one-number. You must use the two-number HP-41C register
addresses.
The function on the HP-67/HP-97 exchanges the primary and
secondary register contents. This same operation can be accomplished
by executing the compatibility function on the HP-41C. It
exchanges the contents of Ry, through Ryg with R;, through R,.
Program Length
Because of the need to translate HP-67/HP-97 programs, the length of
the program once translated will increase slightly over the original
length. You can estimate how long an HP-67/HP-97 program will be
when translated by multiplying the number of steps in the original pro-
gram by 0.2. For example, a 100-line HP-67/HP-97 program will
require 0.2 X 100 or about 20 registers of program memory in the
HP-41C.
Even though the translated programs are slightly longer, they will
normally execute significantly faster than on the HP-67/HP-97.
