The etymology of the word code is most interesting. It seems evident that in its original form it has reference to the paginated format of a book as distinguished from the earlier scrolls. Books with leaves fastened together at a common edge were apparently used in Roman times to record compilations of laws, and this is the basis for the original meanings of code, as a systematic collection, compilation, or formulation of laws, principles, rules or regulations.

This technique outlines a method whereby equation sets can be ordered in computational order and checked for compatibility. The technique also allows one to note what equations can be computed in parallel (provided one has parallel arithmetic capabilities) or can be considered a logical entity, i.e., segment. Furthermore, the technique will assist one to intelligently allocate high-speed memory (HSM) so that memory is reassigned to other duties as soon as its present duties are fulfilled. Last, the technique appears to be simple and fast to implement.

Standard methods of counting binary ones on a computer with a 704 type instruction code require an inner loop which is carried out once for each bit in the machine word. Program 1 (written in SAP language for purposes of illustration) is an example of such a standard program.
