Is it possible to take a piece of a string, and get the length of a string?
I know they have that for the TI-84 plus.
Can you give me the syntax, or at least where to find it?

You can use string.sub to get substrings, and string.len or the lenght operator (#).

local s = string.sub(your_string, pos1, pos2)
print("The substring is: ", s)
print("It's lenght is: ", #s)

Length usage:

string = "cabbage"
return string:len()
> returns 7

If you take substrings, be aware of this bug.
