Re: Ada and Internet stuff

My ARM says: "type Stream_Element is mod implementation-defined;" which
would seem to suggest that an implementation is free to do anything they
please. I think it would be foolish to use anything other than a size that
lines up with your memory units and/or communications hardware and I'd be
willing to bet a fair amount of money that the majority of Ada
implementations are going to use 8-bit bytes for this.

I could see reasons why an implementation might want to make Stream_Element
8-bits no matter what the internal storage unit size is. Streams are going
to get used primarily for two things: Data in files and data along
communication links. The bulk of that is going to be in 8-bit bytes, given
the common trend in hardware. So I doubt there is any expressed or implied
relationship between Stream_Element and Storage_Unit.
