521    the requested bits are not available.  The typical use of the BITS macros
529    input left to load n bits into the accumulator, or it continues.  BITS(n)
530    gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
531    the low n bits off the accumulator.  INITBITS() clears the accumulator
532    and sets the number of available bits to zero.  BYTEBITS() discards just
