Allows you to quickly find the procedures and code lines that have been changed when reviewing code. 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. Compare allows you to quickly find the procedures and code lines that have been changed. It does this by first breaking each file into procedures. Then the procedures are compared. This eliminates many false matches. It does not matter if the order of processes has been changed or even if procedures are added or removed. Within each file, many types of non-significant differences can be eliminated. For display, there is an option to only show the procedures that have changes, and only the changed lines within them. Other features include: the ability to number lines, either by procedure or for an entire file\; and a flexible display that lets you arrange the display view with horizontal windows, vertical windows or a combined window. This makes it very easy to see changes by code line, by procedures, or between code files\; and customization lets you choose your own display fonts, as well as styles, background and text colors to emphasize the changes between the compared code files.
