SORTED TABLE: Unlike standard tables, sorted table have no default setting for the uniqueness ATTRIBUTE. If you do not specify either UNIQUE or NON-UNIQUE, the system defines a generic table TYPE, where uniqueness is irrelevant. You can use generic types to specify the type of generic subroutine parameters. HASHED TABLE: Hashed tables have no default setting. You must use the UNIQUE addition with hashed tables. You may not use NON-UNIQUE. STANDARD TABLE: The key is, by default, set to NON-UNIQUE. You may not use the UNIQUE addition.
