Data Types, Variables and Constants

When you declare a variable, you must state its type. A variable's type determines the set of values it can have and the operations that can be performed on it. Every expression and every function returns a value of a particular type.

DataFlex Types fall into these categories:

• Simple Types
• Folded Integer Type
• Structured Types
• Array Types
