Hello! I see that BinIO is not implemented in MLTon. And I can't see where TextIO is implemented. Where can I find TextIO and implement BinIO myself? I guess it's very simple - except if Word8 and/or Word8Vector is missing too (I haven't checked...). If they're not implemented either, I would like to know where and how I might add these too... :) Cheers -- http://www.HardcoreProcessing.com
