Is a string the smallest way to encode a series of numbers into a program? I don't need to be able to write back to it, I just need to have a list of a lot (I'm thinking 96) of numbers (1- that my program can read from.
A string is quite a bit smaller than a list, but it's still pretty massive.
Maybe some kind of an algorithim? It seems like kind of a waste to only need 3 bits out of every bite.
Any help would be greatly appreciated.
Thanks!

| correction, if u use a list, then it is 3 bits, for every 9 bytes! ouch! |

| you could come up with some crazy algorithm to compress it or something that may save a few bytes but take longer or use a string. I'd just use the string. |

A string wouldn't be a bad idea, because it's fast, and you could archive it when you exiting the program! That would only add 100 bytes or so to the archive and temporary RAM storage. If you are just going to read the numbers, you a polar graphing varaiable too! (In the VARS menu)
Hope it helps, Tyler  |

Yeah I knew a list was completely out of the question.

Yeah but it was the massive line storing "123456...."->Str1 that I was trying to avoid. I guess it's not that important though, I'll see what I can do.
Thanks!

here:
Code:
"{->Str2
For(A,1,dim(LLIST
LLIST(A->N
prgm(theta)N2S
Str2+Str1+",->Str2
End
simple decompress:
Code:
expr(Str2->LLIST
for my number-2-string program (prgm(theta)N2S),
tell me to post it and i will.

here is the code anyways:
Code:
" ->Str1
fPart(N->A
iPart(N->C
abs(N->B
While iPart(B>1
.1B->B
End
Repeat not(B
If Str1<>"(space)
Then
If A and A=fPart(B) and expr(Str1)=iPart(N
Str1+".->Str1
End
B-iPart(B->B
10B->B
Str1+sub("0123456789",iPart(B)+1,1->Str1
If length(Str1)>1 and sub(Str1,1,1)="(space)
sub(Str1,2,length(Str1)-1->Str1
End
If N<0
Str1+"(negative symbol)->Str1
DelVar AWhile N and not(fPart(.1N
.1N->N
A+1->A
End
A->C //this line and the following while loop can be left out if u do not need N anymore
While C
10N->N
End
While A-1(is greater than or equal to sign (>=))1
Str1+"0->Str1
A-1->A
End
sub(Str1,1,length(Str1)-1->Str1
note: if u use this code give me some credit just as im giving credit to jbirk for helping me with my zero detection code (detects ending zeros on the end of whole numbers (i.e. 10) |

Thanks, but I was planning to start out with a string anyway. Like I said, it was the big line storing "12345..."->Str1 that I cared about.
I guess 100 bytes or so isn't too bad.

| IF it was a serise of 1s and 0s on a strink, then I can give you a compressio routine I created that does 80% compression regardless of composition! |

pascal, could u edit it so that it un/compresses a pic into a string and put a link?
i.e.:
Code:
[data]->Str0
1:asm(prgm(theta)piccomp
RecallPic 0
