Defining Rules with Expressions

Expressions are used to create rules and other constraints within your task. You use expressions to produce unique recognition rules, and last page and selection rules, to help define tables, as well as to define other properties of your task. Properties that are designated as rules must evaluate to true or false.

These small distinctions have a significant impact on how expressions are evaluated.
