About Variables and Data Types

A variable is a named, temporary location in the computer's memory where data is stored. Data can be stored in many forms (data types) such as ASCII characters, integers, and real numbers. A variable must have a data type, such as char, long, float, word, short, string, or variant. To provide for efficient storage of data, ATEasy supports a variety of basic data types and creation of user-defined data types.

This chapter describes how to create variables and ATEasy user-defined data types. It includes the following topics:
