Summary:

Need code/ideas that will allow me to run xyzprogram from my base program and then return to the original without adding a "return" button to xyzprogram

So, basically, I've created a nifty little operating system in BASIC called Panda. Right now, it has basic capabilities to edit/save text files, read calculator "mail", track finances, keep a todo list, basic calculator functions, password protected, shutdown, and reinstall itself.

however, to really take it to the next level, i want to implement a thing called "bamboo", which may sound corny, but Panda will "feed" other programs from it, kind of like mirage os… for example, if your calculator has "mario" on it, you could run prgmMARIO from the Panda games menu…

this is all simple enough, just add a "return" command - however, is there a way to do this so that i could reference ANY program without messing with the code?

so far i have tried the following, to no avail

:Input "Game?", Str1
:"prgm" + str1 -> str1
:disp str1
??????????????????????

please please please help me…

oh, and if anyone has any other suggestions on possible Panda capabilities, please let me know…

No way to do it without running an assembly program. Pure TI-Basic shells usually have an extra program which the user would edit to add programs to it. Something like this:

:If A=1:Then
:Asm(prgmMARIO
:Return
:End
:If A=2:Then
:prgmNIBBLES
:Return
:End
...

ok, so if i had to add all the game commands myself, wouldn't the thing give me an error if someone tried to run a game that wasn't on their system?

is there a way to check and see if the person has a certain program?

Yes, it will give you an error message if the person doesn't have the program, and that's one of the main reasons TI-Basic shells never caught on. The only way to check to see if the person has the necessary program is with assembly.

I just remembered that Patrick Stone created a shell making tutorial that might be of some help to you.

thank you so much. i hope to get into assembly soon, but BASIC is so much more convenient because i can do it anywhere, as opposed to having to have my laptop with me.

Are you using the i character, or a lowercase i?

I know that on the TI-83 series, many of the ways you have already tried would have worked. Perhaps the construction of the polar (a.k.a. "phasor") form of complex numbers will help:

(1)

\begin{align} x+\iota y=\left|x+\iota y\right|e^{\iota\tan^{-1}\left(\frac{y}{x}\right)} \end{align}

(2)

\begin{align} \left|x+\iota y\right|=\text{abs(}x+\iota y\text{)}=\sqrt{x^2+y^2} \end{align}

@TI-polar: Unfortunately, there aren't many tutorials or resources for programming on the TI-Nspire, so we are rather limited in trying to help you. The most promising one that I have found so far is John Hanna's TI-nspire page.

Looking at the ▶Polar command in the TI-Nspire reference guide, it says that ▶Polar is a display-format instruction, and not a conversion function. This makes it sound like it only works on the home screen, and not from inside a program. Have you tried the ▶Polar command using that syntax outside of your program?

Well, why did you decide to get a TI-Nspire instead of a TI-84 or TI-89? Is this your first TI graphing calculator?

TI-Connect actually works on Vista, although getting it to work requires that you know what you are doing — see www.ticalc.org/pub/text/misc/ticonnectvistasetup.pdf for more information.

(Note: ticalc.org doesn't allow hotlinking, so that's why I didn't link to it.)
