It is a fact that reviewing code by comparison is one of the best ways to ensure quality. When programs are modified, bugs often creep in. It is a difficult and time consuming task to review an entire program when changes have only been made to a few routines - and which routines? Compare allows you to quickly zero in on the procedures and code lines that have been changed.

• Comparison - Show what lines have been changed (added, deleted and unequal) and what lines have not been changed (equal). Also, see what lines have not been considered in the compare process (ignored). This can help you zero in on the non-cosmetic changes in your code.
• Line Numbering - For ease in reference, lines may be numbered, either by procedure or for an entire file.
• Flexible Display - You may arrange the display view with horizontal windows, vertical windows or a combined window. The result makes it very easy to see changes by code line, by procedures, or between code files.
• Customization - Compare lets you choose your own display fonts, as well as styles, background and text colors to emphasize the changes between the compared code files.
