*LOL*
I only later realised that exchanging my zeros with hex F6 was not
justified. I was talking about 0 as a _bit_ (no charge), not 0 as a _byte_
(ASCII character). Then again, maybe I misunderstood it all in that
context.
My first introduction to hex was in Norton Commander when I was probably
11ish. The file viewer displayed binary also in hex mode unless the file
was readable in ASCII encoding.
