    doesn't a Byte having 8 bits

    Yes, so it is coded 0x00 to 0xFF (hexa representation) or 0b00000000 to 0b11111111 (binary representation).

          BOOL is fully featured integer, for instance, you can do.

          // WEIRD BOOL (legal) programming
          BOOL b;
          b = 1000;
          b++;

          You can't do the same with a bool variable. [added] Well, I made a sanity check, and actually VC++ compiler gives just a warning on the following code

          bool b;
          b = 1000; // Warning here (loss of info), at runtime b becomes true.
          b++; // at runtime b remains true.

          [/added] As stated by someone (Rajesh ? toxcct?) this is a reminiscence of the C language gold ol days (C has not the bool keyword). Using an int to represent Yes/No pair is simply a matter of convention (and convenience). :)

          If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
          This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke

                but one has to be careful with BOOL, as I stated at the end of my most here[^]

                  Indeed. C language implicit mapping of non-zero values to true and zero value to false is more coherent.
