HP HP-67 User Manual

302 Interchangeable Software
For example, if you loaded the program for the area of a sphere
into an HP-67 from the keyboard, then recorded it onto a magnetic
card, and finally passed the card through the card reader of an HP-97,
the contents of the program memory of the two calculators might
look like this:
HP-67 Program Memory HP-97 Program Memory
Step Instruction Keycode Step Instruction Keycode
001 B 312511 oo1 o 21 11
002 @ 3254 002 E% 53
003 B 3573 003 [ 16-24
004 £ 71 004 £3 -35
005 O 3522 | 005 (&0 24
You can see that the program is exactly the same in the two calcu-
lators, even though some operations are prefixed in one calculator
and not in the other. Operations are always loaded correctly for the
particular calculator, so you can examine and edit the program, no
matter the model calculator into which it is loaded. For a complete
list of keycodes and corresponding functions on the two calculators,
refer to appendix E.
Print and Automatic Review Functions
The only functions that operate differently between the two calcu-
lators are the automatic review functions and (5] pause on the HP-67,
and the print functions on the HP-97. For example, you can print a
list of the stack contents with the printer on the HP-97 by using the
PRINT: function. Since the HP-67 Programmable Pocket
Calculator does not have a printer, however, the stack contents are
reviewed by passing them through the display, one register at a time,
with the (automatic stack review) function.
