This option toggles the state of a Text Mode compare or 3-Way Text Mode compare to be displayed using relational lines rather than by performing a line-by-line comparison. A normal text comparison searches line-by-line for differences between compared files:
If Relational Lines Mode is selected, UltraCompare attempts to find matches between the content of the compared files and exclude this from the difference comparison while indicating related blocks and the differences between them visually:
There are two primary differences to be noted in Relational Lines Mode:
The graphical navigation map [1] changes to show navigation maps for both compared files side-by-side rather than a composite difference map for the two files. This allows a separate location block (red rectangle) for each file as well as pointing out graphically where differences occur between the two files.
Differenced blocks that UltraCompare identifies as existing between matching sections of text in the compared files are bordered by lines of the same color as the lines connecting related blocks. The color for these can be set under Color in the Options menu.
Where differenced blocks are offset (not parallel in the display) double-clicking on the connecting line will cause the related blocks in each file to be centered in the display panes.
