12.2.66 byte, byte-size, byte-position | Function
  Syntax: byte size position bytespec byte-size bytespec size byte-position bytespec position Arguments and Values: size, position - a non-negative integer. bytespec - a byte specifier. Description: byte returns a byte specifier that indicates a byte of width size and whose bits have weights 2position + size - 1 through 2position, and whose representation is implementation-dependent. byte-size returns the number of bits specified by bytespec. byte-position returns the position specified by bytespec. Examples:
       (setq b (byte 100 200))  #<BYTE-SPECIFIER size 100 position 200>
       (byte-size b)  100
       (byte-position b)  200
  See Also: ldb, dpb Notes:
       (byte-size (byte j k)) ==j
       (byte-position (byte j k)) ==k
  A byte of size of `0` is permissible; it refers to a byte of width zero. For example,
       (ldb (byte 0 3) #o7777)  0
       (dpb #o7777 (byte 0 3) 0)  0
Allegro CL Implementation Details: None.
