Executing Programs Containing Wand Functions With No Wand Present
Remember from the beginning of this section that the wand functions only become available while the wand is plugged in. So if you
have programs stored in program memory that contain specific wand functions, and the wand is not attached, those wand functions
are nonexistent and that program will not execute properly (when a wand function is encountered, the display will show
NONEXISTENT
). However, when you plug the wand back in and execute that program, it will execute properly. Here is how the
HP-41C keeps track of these wand functions:
1. While the wand is in place, the function name appears normally in program memory, like this:
18 WNDDTA
, or
27 WNDSUB
.
2. While the wand is removed, these functions are displayed in PRGM mode as a function called XROM. An XROM function
tells the HP-41C that the function belongs to some plug-in accessory. Next to the XROM function name are two numbers.
These indicate which accessory the function belongs to as well as an indicator of the function. So, the program line
18 WNDDTA
(with the wand plugged in) would change to
18 XROM 27,01
while the wand was removed. The
XROM
tells the system that the
function belongs to a plug-in accessory, and the
27,01
tells the system that that accessory is number
27
(the wand) and the
function number is
01
(
WNDDTA
).
Programs containing these function have the following XROM numbers while the wand is removed:
Function
XROM Number
WNDDTA
XROM 27,01
WNDDTX
XROM 27,02
WNDLNK
XROM 27,03
WNDSUB
XROM 27,04
WNDSCN
XROM 27,05
WNDDTST
XROM 27,06
