HP-67/HP-97 Compatibility 37
Positioning the Calculator. The HP-41C must be set within the trans-
lated program before the local label execution (A through E and a through
e) of that program can be accomplished. When the HP-67/HP-97 pro-
gram card is read and translated, the HP-41C is automatically positioned
to the top of that program.
However, if you position the calculator outside of the translated pro-
gram, you must reposition to execute the translated program. One way
this can be accomplished is to execute 1. This catalog lists and
automatically positions the HP-41C to successive programs in memory.
If there are only two or three programs in program memory, you will
need to stop the catalog listing immediately after executing 1
by pressing (R7/s]. You can then use and to display and
position to specific programs in the catalog. Since the translated program
has only local ALPHA and numeric labels, no label appears in the
catalog. However, the END associated with that program will appear in
the catalog. If you position to the END of the program using the catalog,
you can execute it using the local labels in USER mode (simply press A
through E, a through e as explained earlier).
Once you have positioned the calculator using catalog 1, you can check
to see if the calculatoris positioned to the proper program by setting the
HP-41C to PRGM mode. The first line of the program will be 07 LEL 67.
Using and in program mode, you can locate that label to
verify that the calculatoris set to the translated program. You can then
switch back to USER mode and execute the program.
Storage Register Compatibility
When an HP-67/HP-97 program card is translated for execution in the
HP-41C, a certain set of data storage registers must be made available for
use in the HP-41C. Before you read the HP-67/HP-97 program card, you
should execute [size] 026 on the HP-41C to ensure that at least 26 data
storage registers (Rq, through R,s5) are available.
