the error condition occurs in the last row of bar code in a program, press
you scan the last row of the program. identify the bypassed program instructions by comparing the
program in the HP-41C with a written listing of the same program. (Where the printed program line
numbers indicate that a numbered program instruction begins on a row you scanned and ends on a
row you bypassed, that entire program instruction is bypassed.) Then go to the place in program
memory where the missing instructions belong and load them using the paper keyboard or the
HP-41C's keyboard.
Note: The system uses a running checksum to monitor program bar code rows for scan errors.
When you bypass a row of program bar code and resume scanning with the following row, the
checksum monitoring system assumes that the row scanned after the bypassed row was correctly
read. When you scan the second row after the bypassed row, normal running checksum
monitoring is reinitialized to the correct running value. For this reason you should compare the
instructions in program memory with a listing of the program to be sure the series of instructions in
the row following the bypassed row were read correctly.
