   BlockAnd - performs a bitwise AND on blocks

   BlockOr - performs a bitwise OR on blocks
             [dest..dest+size-1] := [dest..dest+size-1] OR

              by:  [dest..dest+size-1]
*)

BlockNot
PROCEDURE BlockNot (dest: ADDRESS; size: CARDINAL) ;

(*
   BlockShr - performs a block shift right of, count, bits.
              Where the block is defined as:
              [dest..dest+size-1].
              The block is considered to be an ARRAY OF BYTEs
              which is shifted, bit at a time over each byte in
              turn.  The left most byte is considered the byte
              located at the lowest address.
              If you require an endianness SHIFT use
              the SYSTEM.SHIFT procedure and declare the
              block as a POINTER TO set type.

BlockShr
PROCEDURE BlockShr (dest: ADDRESS; size, count: CARDINAL) ;

(*
   BlockShl - performs a block shift left of, count, bits.
              Where the block is defined as:
              [dest..dest+size-1].
              The block is considered to be an ARRAY OF BYTEs
              which is shifted, bit at a time over each byte in
              turn.  The left most byte is considered the byte

              block as a POINTER TO set type.

(*
   BlockRor - performs a block rotate right of, count, bits.
              Where the block is defined as:
              [dest..dest+size-1].
              The block is considered to be an ARRAY OF BYTEs
              which is rotated, bit at a time over each byte in
              turn.  The left most byte is considered the byte
              located at the lowest address.
              If you require an endianness ROTATE use
              the SYSTEM.ROTATE procedure and declare the
              block as a POINTER TO set type.
