I'm having a very annoying error in my ti-84 plus:
What I tried to do and works (1 time),
is to replace characters in a string with sub etc.
But it only works one time, when it's the first character!
Then it gives invalid dim on the last bracket!
My code: Sub(Str1,1,H-1)+" "+sub(Str1,H+1,length(Str1)-1)->Str1
Str1 = ABBA
If H = 1 it works, if H = something like else: 4 it doesn't work
Between the " " can be the character you want to replace with and H is the place of the character you want to replace, in my case A
With H = 1
Solution = *space*BBA
Thanks in advance!
