An apparatus accepts randomly arriving blacks of parallel digital data of varying
bit lengths termed datum segments that may have been generated by stripping leading
zeros from bytes of a fixed size, each having associated therewith a bit count
code that expresses the bit length of each datum segment in the form nnnnndddd
. . . , the "n" being the bits of the bit count code in such number as to encompass
the memory capacity of a receiving device to which the datum segments are to be
sent, and the "d" representing the actual datum segment bits. The apparatus concatenates
the nnnnndddd . . . expressions to form a continuous bit sequence that is saved
so that each nnnnndddd . . . expression is accessible thereafter through the computer
address therefor, such use preferably being by a circuit of matching bit length,
the format, however, allowing the original form of the data to be recovered if desired.
