ok guys, i have looked at tutorials, ticalc, the manual, and posts on this site, and tries myself, but i cannot find how one finds a specific point in a string, say "ABCD"->Str0 i would like to change the 3rd one from C to N. i believe this has something to do with the dim( function, but i just cant find it!

say you have the following string:
"ABCDEFGHIJKLMNOPQRSTUVWXYZ->Str0

If you want to know the place of the first D in the string, you could use this:

instring(str0,"D->A

A=4

It's like doing this:
1
While not(Ans>length("ABCDEFGHIJKLMNOPQRSTUVWXYZ") or sub("ABCDEFGHIJKLMNOPQRSTUVWXYZ",Ans,1)="D")
Ans+1
End
If Ans>length("ABCDEFGHIJKLMNOPQRSTUVWXYZ"):0

Hmm, yes, strange I wrote that.

The above also shows better why it can be usefull with instring, you can just replace the 2 with instring-1 and the 4 with instring+1 and it'll replace the character.

"AHDSFJ->Str0
instring(Str0,"D
sub(Str0,1,Ans-1)+"D"+sub(Str0,Ans+1,length(Str0)-Ans->Str0

that only works correctly if you never choose the first character.

you must write 2 routines for that.

(3 because of the last character as well Laughing)

Though I've never had problems with that, you could just do this:

" " + Str0 + " ->Str0
//replace code

Also you need an "If Ans" so it doesn't do your code if the letter is not in there.
