499    the requested bits are not available.  The typical use of the BITS macros
507    input left to load n bits into the accumulator, or it continues.  BITS(n)
508    gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
509    the low n bits off the accumulator.  INITBITS() clears the accumulator
510    and sets the number of available bits to zero.  BYTEBITS() discards just
511    enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
