Combo: A General-Purpose Program for Searching, Annotating, Encoding-Decoding, and Reformatting Data Files (Classic Reprint) - Softcover
Synopsis
Excerpt from Combo: A General-Purpose Program for Searching, Annotating, Encoding-Decoding, and Reformatting Data Files
It is our view that many application programmers' and systems analysts' views on program efficiency are unduly colored by early experience with primitive compilers and computer systems. As computers have become faster and as core have grown larger and cheaper, over-all man machine efficiency considerations often outweigh consideration of Optimum machine use. While these classical concerns are still important for long repetitive computer runs or for processing large files, they are really not important for a large fraction of the day to day Operations on a modern computer. Moreover, we have found that, for nonnumerical applications, on the whole, a special-purpose program written to solve a specific problem will be no simpler than a general-purpose program capable Of solving it and many other related although not identical problems.
General-purpose programming is greatly facilitated by the use of subroutines of modular design. This resembles the construction Of a house from prefabricated parts. Just as certain kinds of wall or flooring components are common to buildings of very different design, certain types of subroutines are widely used in a variety of differing applications. Scientific programmers have largely recognized that the same matrix package may be used for both linear programming and quantum mechanics, and that it is not necessary to write two separate specialized program. Persons writing programs for such applications as file management, selective dissemination of information, information storage and retrieval, and text editing, on the other hand, have made minimal use of modular subroutines. Most of them have preferred to write their programs from scratch, much like a builder refusing to use prefab parts on the assumption they will be the wrong size or shape.
We have found that in non-numerical file manipulation and information retrieval, modular subroutines can be as useful and as versatile as in scientific programming. For example, the substitute program, adapted as a subroutine, can be used for such varied jobs as report generation, correction of errors, and computer-assisted typesetting.

Paperback. Condition: New. Print on Demand. This book gives readers access to COMBO, a unique program that simplifies information retrieval, report generation, and text editing on magnetic tape files. With origins in the diverse data storage formats used for the National Standard Reference Data System, COMBO was designed to facilitate the handling of large and varied data sets. It is especially well-suited for files featuring complex structures and multiple types of lines, each with its own unique format. COMBO users benefit from a vast array of search options that can be applied to individual lines or whole records. Using advanced Boolean logic, the program identifies items that satisfy user-defined criteria. The text editing capabilities extend to string substitution, reformatting, and the insertion of specified values between fragments of text, providing researchers with unparalleled flexibility in tailoring output to their specific needs. Additionally, COMBO simplifies the division of data files, allowing users to isolate sections based on line types and direct them to different output devices, including printers and magnetic tapes. This book offers a comprehensive guide to the use of COMBO and its various features, making it an essential resource for researchers and data analysts working with complex data files. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781528423786_0
