Bytes (was: password in a script)

[Jan Schenkel]

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 revUp newsletter article that I wrote a while back:
