IO (API)
From ComputerCraft Wiki
IO is a reimplementation of the default Lua input / output API defined here, with some features trimmed. Most features should work. If you find a non-working feature, please list it here.
List of non-working features from IO:
- file:seek(...) - Doesn't exist.
- io.lines(...) - Doesn't exist either.
- io.read("*all") - read() does not work with "*all" argument; use "*a" instead.
- io.open("FILE_NAME", "a+") - Append+ mode is unsupported.
- file:read(...) - Doesn't seem to exist in 1.43.
If any functions don't exist try the Fs API instead.
