This chapter introduces the basic syntax you used to create application components, declare their data types, and reference them once they are created. These include:
• Simple application components, such as simple fields and simple local and global variables.
• Complex components, such as table fields, record types, complex local and global variables, arrays, and constants.
For information about specific statement types—including database access and forms-control statements—see Writing 4GL Statements. For the full syntax of each 4GL statement, see 4GL Statement Glossary.
