A practical guide to formatting data with a programmable approach. This edition explains how Reform reads, reorganizes, and outputs data using control cards.
The book presents a hands-on look at how a data-deck-driven program handles input, output, and the transformation of records. It outlines the structure of input and output formats, the role of strings and fields, and how to manage data flows through a pair of subroutines. The material stays focused on practical methods for manipulating formatted data files.
- How to define and map input fields to output cards and strings
- How the program reads, stores, and reformats data blocks
- How control cards influence reading, punching, and printing actions
- Concrete examples of input plans, field widths, and data decks
Ideal for readers who want a concrete walkthrough of data formatting programs and their control logic.
