Reading A Program Fromacard - HP 82104A Owner's Handbook Manual

14 Card Reader Operations
3. Execute the (write private program) function (
WPRV (acpra])). The HP-41C will prompt you with
RDY kk OF nn
where kk is the next track number and nn is the total number of
tracks required to write the complete program to cards.
4. Insert track 1 as shown. If the
program is longer than 16
registers, the HP-41C will
prompt you for subsequent
tracks with ADY kk OF nn,
5. The entire program, including
program key reassignments, is
now written on the magnetic
cards and is made a private
card.
The private card may be read and executed any number of times, but
cannot be viewed or altered. In addition, you cannot write an already
private program to a new card. Any attempt to view (e.g., (SsT], (BsT)),
alter or record this program will result in the display of the PRIVATE
message. The function is not programmable, that is, cannot be
keyed in as part of a program.
Reading a Program From a Card
Once a program is written onto a card, it is a simple matter to read that
program back into the HP-41C's program memory.
Here is one procedure for reading programs from magnetic cards:
1. Ensure that the HP-41C is not in PRGM mode.
2. Press @B (] (=] This positions the HP-41C after the last
program in program memory. The program that is read in will be
placed after the last program in program memory. If you do not
do this step, the program you read in will replace the last
program in program memory.
