So, I've read the chat logs earlier and Tim Wessman said some things about weird things that could happen in functions/plots

[08:21:15]<tw_hpcalc>i am quite excited to get more people pounding on it with the user programs, but also nervous
[08:21:24]<tw_hpcalc>   as user programs are one of the hardest things to allow
[08:21:34]<tw_hpcalc>   so many ways people can do things you never anticipated
[08:23:25]<tw_hpcalc>   so here's a good one for example
[08:23:35]<tw_hpcalc>   you can make a user program, and graph the thing
[08:23:58]<tw_hpcalc>   put the function call inside your equation, and have that create user dialogs....
[08:24:10]<tw_hpcalc>   what's going to happen there? :-|
[08:24:21]<tw_hpcalc>   just crazy stuff like that

So far... no luck in finding anything weird in that (well, at least on the computer software, but at this level it shouldn't matter)

Indeed I can call a function I defined earlier from a plot (within F1(X) for example), and as long as the program RETURNs something, it can be used.
However... that stops working as soon as there is some I/O commands in there. (Then, the graph (and table) says the values are undefined)


I have a question, though, if TW ever reads this : a function(X) returning TICKS() and then plotted will only produce one point ... Any idea why ?
And... weird behavious finally found : With a single-screen (plot) : I can't autoscale because of this ^ (it says it can't because there is one point). However, when looking at a split view, with table, it then produces more values (it's funny because when you click, or do whatever, it updates the values . And then, *sometimes* you can use autoscale., don't ask me why Looks like this :

(Also, you still can click and move around even if that popup text is displayed)



Anyway, any other cool ideas of crazy things to try ?


PS : What about syntax-coloring in the program editor ... ? Would be darn cool/useful.

Scrolling in the HP-Prime program editor is quite slow too.

[...]while with the calc you need to remember the reset combo or carry a needle with you to push the reset button.

Protip: mechanical pencils

Speaking of the emulator, when the calc's out is it going to be a Ti- or Casio-style locked down thing that costs twice as much as the hardware?

I was meaning more along the lines of the emu. TI and Casio both have windows-only (and maybe mac) emus that cost about twice as much as the calc.

Did you try one of the metal-tipped pencils? Those things can fit pretty much everywhere, esp if you use the lead.

Well, if [ON]+[Symb] somehow makes a hard reset... it's no problem

this key combination needs to be visible in every page of the wiki at the top, as notification

oh I don't know about those pencils but IIRC even those won't fit. It's kinda like my old router.

As for the OS compatibility apparently the emu works perfectly on Wine (or at least it works as well as in Windows).
