Getting one char from specified position

Question

I'd to reach a char from a string in corona. Basically I want to:

local mystr = "corona"
print( mystr[3] )

But it always returns nil. How can I achieve that?

Here is simple logic that I used for the same purpose. Hope this may help you:

local mystr   = "corona"
local str_tbl = {}
for i=1,string.len (mystr) do
    str_tbl[i] = mystr:sub(i, i)
    print("Character in position "..i.."is:"..str_tbl[i])
end

Thanks, I think mystr[3] is like mystr:sub(3,3) – Doğancan Arabacı Sep 18 '13 at 11:34
