Keycodes for these keys are shown
with a minus sign before them.
Keycodes representing keys on the left keyboard of the HP-97 have
keycodes with no sign before them, so a 3 instruction loaded
into the HP-97 would have a keycode of 36 03. If that operation were
recorded onto a magnetic card, and then loaded from the card into
an HP-67, the keycode for the operation in the HP-67 would be 34 03.
Although the keycodes are altered, the operations are the same from
calculator to calculator, from HP-67 to HP-97. And since each opera-
tion, no matter how many keystrokes it takes to perform, is loaded
into a single step of program memory, the steps of program memory
into
which
a
program
is
loaded
are
the
same
when
a
program
is
changed from one calculator to another.
