The 'byte' chunk type and friends ('byteToNum' and 'numToByte') were introduced
in Revolution 3.0 - and guarantee linear access to a piece in a container
(variable, field, etc)
The idea is to let you retrieve individual bytes in a container, even when
there's a mix of ASCII and Unicode in there. Right now, 'byte' and 'char' are
the same, unless the local property 'useUnicode' is set to true. But in the
future, Mark Waddingham wants to make 'char' adaptive to the encoding of the
container or even part of the container.
So if you're processing binary data using 'char' right now to get to individual
bytes, you should move over to 'byte' to avoid future surprises. See also the
