ULTRIX Worksystem Software Guide to the dxdiff Visual Differences Program

This document is a user guide for dxdiff, a visual differences program that is part of the ULTRIX Worksystem Software (Version 2.2), designed to run on ULTRIX-32 (Version 3.1 or higher) within the DECwindows environment.

Aimed at ULTRIX end users and programmers familiar with DECwindows, the guide explains how to use dxdiff to graphically compare two ASCII text files line by line. It describes how the program highlights differences as areas of text, connected by lines or filled polygons, in a two-pane display.

The manual covers essential tasks including:

• Starting the dxdiff application.
• Selecting files for comparison.
• Displaying and navigating through the differences.
• Changing display characteristics (e.g., linked/unlinked scrolling, rendering differences as lines or filled polygons, showing line numbers).
• Comparing new sets of files (either in the current window or a new one).
• Exiting dxdiff.
• Customizing the program's appearance via entries in the .Xdefaults file.
