ULTRIX Worksystem Software Guide to the dxdiff Visual Differences Program

This document is the "Guide to the dxdiff Visual Differences Program," part of the ULTRIX Worksystem Software, Version 2.0, published by Digital Equipment Corporation in 1988.

It serves as a manual for ULTRIX end users or programmers familiar with DECwindows, describing how to use dxdiff to visually compare different versions of ASCII text files. The dxdiff application utilizes the diff(1) program to identify line-by-line differences, presenting them graphically as highlighted text areas connected by lines or filled polygons.

The guide covers essential tasks such as:

• Starting the dxdiff application.
• Selecting two files for comparison.
• Displaying and navigating through the identified differences.
• Customizing the display characteristics (e.g., linked/unlinked scrolling, visual representation of differences, line numbers).
• Comparing new sets of files (in the current or a new window).
• Exiting the program.
• Customizing dxdiff's appearance by modifying entries in the .Xdefaults file.
