Re: HP calc. Customer Service

Hi,

I have tried writing the Hello World program in Notes. I can save the
file, but there is no way to tokenize it, it seems (at least no menu
entry offers to do just that). Then I have used the Define command in
the CAS. For instance, you can write there:

Define g(x)=x*x Done

and when you write g(2), the calc answers with 4.

When I Defined the Hello World program with
Define hello()=Prgm:text "Hello World":EndPrgm,

the calculator did not answer with "Done", as above, but with
"endprgm". It seems that either it has recognized a special construct
(prgm...endprgm) or it has just repeated the last colon-separated part
of the definition. Anyhow, when I now write hello(), it replies with
"text·"Hello World". So my guess is the software has recognized the
Prgm...EndPrgm construct, but sees no way to really execute it. By the
way, all keyword letters are de-capitalized after entry.

What do you think? How could I possibly *call*/execute that defined
function?

Thanks for the information.
It is surprising that 3D plotting is not easily availlable as it is one
of my favorite feature of those advanced calc and in fact one of the
main marketing argument for the TI92 when it was introduced in 1995.
For programming of the Tool assuming that it has a similar user
language to the TI92,you can find some help from the TI89TI/Voyage 200
guidebook availlable from the TI site here:
http://education.ti.com/educationportal/appsdelivery/download/download_eula.jsp?cid=us&displayMode=G&applicationid=6128&contentpaneid=17

Eventually i could give you additionnal help if needed as i happen to
be quite strong with TI92 Basic.
I think that you could write programs with the Note editor then
tokenize and save them from the calculator screen.
For exemple the famous Hello world:
Define hello()=Prgm:
Text "Hello Wolrd":EndPrgm
Execute from the calculator apps,this should create the program which
when called as
hello() should show a window with the message.

Hi Jean-Yves,

no touch sreen, just a small circular plastic pad which is sensitive to
finger presses and with which you can push the pointer arrow on the
screen into any direction (diagonally works, too). There are additional
arrow keys which basically do the same thing but much more slowly
(pixel-wise). The pointer speed is ok now, but will be too slow when I
have gotten used to it, I think. There is no way to change the speed,
although there are a couple of other general "system settings". The
device is completely menu-driven, just like any ordinary PC, you can
have any number of documents open at one time, among them a
spread***, which is much like Excel. It features local and global
cell references, and the whole apparatus for symbolic math (the CAS
core) can be used in any cell. There is an automated sequence generator
for the spread***, too, which is nice when doing pseudo-random test
series. The basic principle is that you have a "problem" (that's how TI
calls the Nspire documents, I hope the docs won't cause any) to which
you can assign up to four different applications (CAS, graphics,
spread***, and notes). Changes in variables, definitions and so forth
in any of the environments immediately and dynamically affect all
assigned applications.

In fact, I like the device a lot so far. It features a big clear
screen, which is just a tad too dark for me and could have been coated
in a way to better prevent light reflections. It seems to be
programmable (there are flow control constructs, Goto Label command,
and the like). I just have not written any program yet, and don't know
how to (where to write it and how to run it and so on), since there is
no written documentation with the calculator, and the last TI I have
programmed was the TI 66. In fact, I learned programming on that
calc... nostalgia... Can anyone point me to programming ressources for
the Voyage or the TI-92? Maybe the systems will turn out to be similar.
I have not noted any options for assembler programming (which is one of
my favorite pastimes).

I have found numerous graphics plotting capabilities, but none dealing
with 3D so far. But then, I had the Nspire running for only 30 minutes
roughly yet.

Hi Michael.

Thank you for your post.

It looks like TI made the best use of the waiting time and created a
learning device similar to what Xpander should have been.
Is the calculator using a touch screen or like what it appears on photo
just a little joystick? if yes, how does it work? do you like it?

Does it have a spread***? how does it work?


Too bad HP was left behind technologically. I agree with your earlier
comments.
