User-defined types (aliases)

DEFINE ALIAS statement

An alias is a type name that can be used wherever an explicit data type is allowed. Using the DEFINE ALIAS statement, you can define an alias for a collection of data attributes. In this way, you can assign meaningful names to data types and improve the understandability of a program. By defining an alias, you can also provide a shorter notation for a set of data attributes, which can decrease typographical errors.
