Thanks Meishe; quick explanation of proof by induction using domino's....heh heh Statement 1: The 1st domino falls over Statement 2: If a domino falls over, the one after it falls over Therefore, all the dominoes fall over So in proofs by induction, you prove that a statement is true for 1 (or 0, as calc84se says), then assume it is true for some constant, k, and the prove it's true for k+1 Calc84se, if what you've said is true, then I just proved Euler's formula w/o any calculus  (kinda random I know but ever since I saw that xkcd where e^(pi i)=-1 I've never been completely satisfied with the explanations (mainly b/c i'm not as advanced in calculus yet >.<)

I suggest moving to a subforum archive and leave a sticky warning the code is "old" and instructions of how to port it to new code.
yeah, I don't want to delete all of the old posts. Gradual phaseout is gradual. But phaseout means..head in one direction, and keep going

k so basically I was wondering if proof by induction is valid if, for the first step, you prove for x=0 instead of x=1. Using domino logic, it's really a matter of whether you decide to start counting from 0 or 1 (which is where I got the idea to ask you guys....  kthxbai

we could have a topic showing equivalent commands.
it could just be like this, but perhaps more organized and alphabetical:
Old__________New
Conj() | Copy()
Repeat | Until
Tangent() | Bitmap()
int() | sign{}
Fill() | Zeroes()
________________________
you'd want two tables, one for alphabetical Old commands, and one for alphabetical New commands.
i like. Just sticky it, and nubs can use it for reference while at the same time vets can try to phase out of the old commands. Really, the only ones that seem to be a major change are the data manipulating commands like Fill and conj speaking of stickies, someone should sticky the "updates" thread again....

happy forum is happy
my 2 cents:
I think that, while the original goal of Axe was to provide a similar style to TI BASIC programmers, this is kind of necessary. Commands like Tangent( do not share any similar syntax between Axe and BASIC, and so it's fine to have the token hook replace this with Bitmap(.
Like DJ said somewhere, i think that many of the tokens that share similar syntaxes, like Repeat and possibly conj( should be switched back.
In other words, practice moderation when changing token names. If, Quigibo, you really are running out of possible intuitive commands, then by all means use the token hook to "make" new ones. At the same time, however, previously established commands should retain their original token.
I feel like this will provide a way for newer members to see less "replaced" tokens, as well as not intro'ing too much of a change for longer-time Axe users. I mean, I always just do "Math" "1" when I think "command to display ASCII," so...yeah

Many of the tokens don't change, such as For, Pt-On, etc, but some notable changes have been <delta>List changing to Data(, and conj( changing to Copy(
Personally, I don't think that many of the changes are an issue, some of them were perhaps a bit unnecessary (like conj( to Copy(, and Repeat to Until.

All right... Since DJ hid all the Axe topics, I don't have access to .3.0 to check out the change. However, I feel like this decision is really the choice of Quigibo. .2.6 is quite functional as it is, and you can just use that if you don't like the new system. (although since I don't have .3.0 I don't know whether there are any really nice new commands) I liked the old idea of using BASIC tokens, but I'm also open to change. It's a practical matter; Quigibo's right in that there simply aren't quite enough intuitive tokens. Either way, I feel like we shouldn't try to split as a community, and I certainly don't really appreciate DJ taking the entire Axe project hostage... I'd really like to get .3.0 to see exactly what has changed...and then I'll cast my vote  edit: Also...is it really that much of a pain with the old posts using the old code? People will get confused but I think they will quickly discover the situation, and also due to the high # of posts about Axe, these old topics would get phased out eventually anyway

i was pretty quick to pull out a battery so no harm done to my calc.
I just hit clear and it exited to Mirage like normal... i guess maybe it's a side effect of rapidly changing contrast? I remember this actually happened to me before while I was experimenting with combining contrast levels and grayscale to produce 8 lvl gray in Axe (it worked, but there's barely any practical use, and you can only display like 6 of the 8 shades at once anyway)

I think it is the blue screen of death. Putting DrawInv
Shade(63)
DispGraph
Repeat getKey
End
Shade(47)before the suspect code lets you see the difference
I tested it on my calc lol (good decision? It hasn't exploded yet...)

So if you had a splash screen stored to, say, Pic1 and said Pic1->DispGraph, it would show Pic1? But I thought you could only store 8x8 sprites to pic pointers...? confused >.<

(I don't own a link cable)
Ah. Missed the implications of this. Also forgot that the 83+ series don't come with the Periodic app preloaded. Also forgot that the 83+ doesn't have the USB connection (lost my link cable a few months back, now I just use my digital camera cable lol) Looking back on my post, i see I was a little brusque. Apologies, and good luck!

Interesting. I don't really see the point of Multitab, though. If you're holding a calculator....then why need a multiplication table? Also, how will Chemitab take input? If it's just a periodic table...then there are apps (specifically Elements 3.0) that do it as well i suppose it would make a great programming excercise, but overall, not too useful...

Are you sure Str2 is exactly 10 characters? Maybe you mistyped it.
there we go...I missed it by one and I guess it messed things up you guys are right, that's only a boiled down version of my actual code but I actually use infinite loops a lot while working on a project since in Mirage I can always just exit using OnMode lol

Quick question on text displaying:
"XXXXX ZZZZZZ YYYYYYY "->Str1
"XXXXX "->Str2
While 1
getkey->K
A+(K=3)-(K=2)->A
conj(A*10+Str1,Str2,10
Text(30,30, Str2
EndThis displays the proper string, but with random garbage characters afterwards, ie, "XXXXX eoppp"
I tried putting in Fill(Str2+9, 32) after the conj( line to overwrite possible garbage in Str2 with spaces, but with no success. Any thoughts?

well nintendo has been decent on backwards-compatibility, although I cried when the DSi came out with no gba slot...don't even mention the DS coming w/o gbc compatibility...but I think it's safe to say that it'll keep w/ DS titles
I don't even have a ds....i want
