Wow... I wish ticalc.org didn't have a limit on # of Authors.
Anyway, I'm haven't been working on the Game pack for a while and probably not until tomorrow, I have a ARML math practice going on, but today's the last day...

btw, if Calc84 didn't post that, I wouldn't noticed, I LOST THE GAME! :'(

You can't escape internet memes bwahahahaha XD

joke aside, I hope you get more free time afterward to program (like everyone else), such as no Summer school or 2-3 jobs at once x.x

Mhmm sorry but I fail to see the point of trying to crash people calcs (altough from the program title it is enough to not want to run on a real calc)

Well, on Wabbitemu 84+, it archived for a while, obviously, then I ran out of RAM, ending up with 149 bytes and Pxl-Off( in my MEM manager (which crashed after an ERR:UNDEFINED after trying to delete it)

I ran it in an emulator, and it ramclears when you scroll down to the appvars, getting overwhelmed, thus you cannot delete them.

The better version of this is just to create lots of appvars, all the same name. (you shouldn't be able to do it, but using "prgmVAR" rather than the correct "vVAR" does the trick.) It doesn't crash your calculator, it just can slow things down a lot and it makes it a pain to delete them, since you go in, delete it, it looks like it's gone, you go in, it's back, you delete it, and so on.
And yes, whyever would you want to clear someone's RAM?

To mess up a calc badly I think you could always just store random crap to every RAM addresses like For(A,0,32767):rand/256->{A}:End. I have doubts the program would even reach 32767 and I do not know what kind of bad stuff will happen x.x

If you want to mess around I really recommend testing on emulator, first.

Btw, anyone knows at which RAM address the calculator current RAM is stored? I know where is the archive (in 4 bytes little-endian hex, if I recall correctly) but I couldn't find the Free RAM amount location on WikiTI.

It would be nice when running a game if we could show the calc RAM in a menu

there is a bcall, MemChk, that returns the amount of free RAM. I'm not sure where the data actually is. (In case anybody wants to come up with hex, the amount of free RAM is returned in HL)

Ok so it isn't stored at a specific RAM address?

I don't know. It would seem like there's a counter somewhere, given the fun I've had with calcsys and no free RAM, (you can even do this in Axe, code below), but I'm not sure where that is either. Is anyone more knowledgeable about this?
Code:
Code: [Select]
.RAMBGONE
"vTEMP"->Str1
GetCalc(Str1,1000)->X
Return!If X
0->{X-2}r
.Previous r is radian r, of course
Delete appvar TEMP, and you'll have 100 bytes fewer free RAM than before. Of course the 1000 can be replaced by any value, including values >9000.
The program works by setting the appvar size to zero after creation, which means there are 1000 bytes of free RAM that the OS doesn't know exists.

That's becasue the symbol table also holds a copy of the size and the OS uses that when calculating how much ram you have.  I'm almost certain that there is no one location that holds the current ram amount.  Instead, I think the bcall calculates the ram available by reading through the entire symbol table each time.

By the way, I think this has kind of gone off topic since this thread is mainly for sharing projects.

yeah it would be good if it went back on-topic (and preferably projects that doesn't involve trying to cause RAM clears and install viruses on people calcs <.<)
