Building Expressions
Expressions are made up of statements, which contain expression terms made up of objects and operators, which can further be refined by selecting methods and attributes.
In this topic, we will cover the general steps of using the expression builder to create an expression. For a detailed example, see Expressions: Detailed Example.
You create an expression by selecting either an If or a Return statement and then building the expression terms in that statement with objects, methods, attributes, and operators.
For details on the data types in an expression, see Data Types for Expression Terms.
