The computer programs accompanying this book implement many of the techniques described in the text. They are adapted from the programs in the first edition of Scaling Methods to run on a personal computer. These programs do not need data in a fixed format, i.e., they all use "list directed" I/O also called variable format data. Each program (with a .exe suffix) uses a small configuration (or runtime control) file (with a .cfg suffix) which provides necessary information to the program. Each program has an accompanying "readme" file (with a .txt suffix) that describes information specific to that program and sample data (.dat suffix) and report files (.out suffix). This document describes characteristics that apply to all of the programs. You should read this entire file before using any of the programs. Español

Requerimientos del sistema: These software programs are stand-alone programs. This means that you can use any one of them independently of the others. It also means that you don't need any additional software for them to run. The only software that you need is a text editor, like Notepad or Edit that come with Microsoft Windows. The computer programs were designed for an Intel Pentium-class PC running Microsoft Windows 95 or later. The computer should have at least 32 MB of main memory and at least 3MB of free space on the hard disk drive. A printer would be useful if you want to print a report or graph and the programs will work with any printer installed in Microsoft Windows.
