To load bar coded numeric or ALPHA data lines in program memory, set the HP-41C to PRGM mode, then scan the data bar code.
Numeric data is stored in program memory as a numeric entry. ALPHA data is stored in program memory as an ALPHA string.
Scanning Program Bar Code
HP-41C program bar code is listed in the following format:
ROW 1
(1 – 6)
ROW 2
(6 – 12)
The occurrence of program line number 6 twice, i.e., at the end of row 1 and the beginning of row 2, indicates that the bar code for
the function on program line 6 is divided between the two rows. To load a bar coded program into your HP-41C:
1.
Ensure that there is enough space in program memory to load the program. (The number of registers required to store the
program is printed above the first row of bar code.)
2.
Scan the rows of barcode sequentially, beginning with row 1. After each
row is scanned, the calculator should sound the scan tone and prompt you
for the next line with:
Where
is the number of the next bar code row to be scanned.
nn
If the HP-41C sounds the scan error tone while you are scanning program bar code, refer to
After you scan the last row of program code, the message
appears. (The HP-41C is set to line 01 of the program.) Scanning a new program clears the last program in memory. However, if you
want to append the new program to those already in memory, execute
