substrings

[drarem]

I thought this would be an easy task.. how do I get a substring, like the 5th byte of a string? Such as this:

 

"ABCDEFG"

 

> return 'E'

 

Thanks

Have you tried string.sub()?

Here's what happens, where fileinput starts out as a table..

 

local astr = fileinput.tostring()

System:Print(astr)

-- looks ok

 

System:Print("as:cahr = :"..string:sub(astr,1,1))

-- error, expecting string got table

change string:sub() to string.sub()

 

you have stringcolonsub(), you need stringperiodsub()
