Using 4GL
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.
