Vectors whose elements are restricted to type
character or a subtype of character
are called strings . Strings are of type string. Figure 15–2 lists some defined names related to strings.
Strings are specialized arrays and might logically have been included in this chapter. However, for purposes of readability most information about strings does not appear in this chapter; see instead Strings.

Vectors whose elements are restricted to type bit are called bit vectors . Bit vectors are of type bit-vector. Figure 15–3 lists some defined names for operations on bit arrays.
