Because of their compactness, bit arrays have a number of applications in areas where space or efficiency is at a premium.
Bit arrays and the operations on them are also important for constructing succinct data structures, which use close to the minimum possible space.
Bit arrays are also a useful abstraction for examining streams of compressed data, which often contain elements that occupy portions of bytes or are not byte-aligned.

Every bit file is referenced by a structure which includes a FILE pointer, a character to buffer bits, and count of the number of bits in the character buffer.
Once 8 bits have been written to the character buffer, the buffer is written to the underlying file and the bit count is set to 0.
The array data is contained inside structure which includes a count of the number of bits in the array, and a pointer to the memory storing the array.

 Bit arrays
Bit array are a fixed-size mutable sequences (Sequence protocol) whose elements are either t or f.
Bit array words are in the bit-arrays vocabulary.
Bit arrays play a special role in the C library interface; they can be used to pass binary data back and forth between Factor and C. See Passing data in byte arrays.

 PASCAL MACRO COMPILER BIT ARRAY MACROS
Using bit arrays provides 8 times as many binary flags or switches in a given amount of storage as using Pascal boolean arrays.
Each bit array must be declared } {in the Pascal program as array[0..N-1] of byte where N is} {the number of bytes in the array.
The macros treat the } {array as 8N separate bits.
