Arkansas Cotton Nitrate Monitoring (CNM) computer programs were originally constructed to use very little computer memory or auxiliary storage. Since that time auxiliary storage and computer memory have become relatively cheap. This has enabled the use of the computer to do data entry, electronic data recording, on line storage, and sorting functions. Our biggest savings of resources has resulted from changing to top-down-block programming structure. This has reduced the time necessary to update, debug and adapt to new requirements to about 15 percent of what it was previously. In addition, debugging is much easier and programming changes are almost error free. Information engineering has pointed out ways to structure input data and output such that errors are minimized while maximizing understandability and the interpretive value of the report.
