Question - How many types of Standard Internal Tables?
Answer -
- STANDARD TABLE:
The key is, by default, set to NON-UNIQUE. You may not use
the UNIQUE addition.
- SORTED TABLE:
Unlike stadard 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.
