WNDSUB
The
wand subroutine function halts program execution so you can use the wand to scan a new subroutine.
WNDSUB
in the same manner as
WNDLNK
1. When
is executed, the HP-41C prompts with
WNDSUB
2. After the new subroutine is scanned, program execution resumes with the first instruction in program memory after the
instruction.

WNDSCN
The
wand scan function is designed for use in specialized applications involving control of the HP-41C system through
WNDSCN
unique patterns of user-created bar code. If you are new to the HP-41C system or to the more technical aspects of bar code design and
generation, you may want to bypass this topic until a later time.
Use of
involves:
WNDSCN
1. Producing your own specialized HP-41C bar code or using the specialized labels included in the pressure-sensitive label set
shipped with your wand.* Instead of translating your bar code into HP-41C functions or data, the wand converts the binary
(base two) value of each byte (set of eight bars) of your specialized bar code into the decimal (base 10) equivalent and stores
this equivalent in one of the HP-41C's data storage registers.
2. Creating an HP-41C program that will use the decimal equivalent from
operations, or whole routines.
*
The label set shipped with your wand includes a series of one-byte labels identified with a number between 1 and 64. Each number is the decimal
equivalent of the binary value of the bar code printed on the label.
