Data library objects expose collections of interfaces (functions) concerned with amorphous data processing.
Central for data libraries operations is the `data' data types, representing byte arrays of recorded length.
Unlike the intrinsic string type data, data of the `data' type may be modified, and (just like data of other libx1f4i0 libraries provided data types) may be referred more than once.
See Of The Intrinsic String Type.
See Referable Objects.
For intrinsic string type interoperability, one extra zero byte is stored at the end of the `data' data byte arrays. The extra zero byte is not counted by the array lengths.
