Initializations
The following statements initialize data objects, that is, they set the content of a data object to an initial value:

CLEAR

FREE

Initialization does not delete the data objects in question. Data objects created by declarative statements are only deleted from the memory when leaving a program, together with the internal session. Objects created dynamically by the statement
CREATE are deleted by the
Garbage Collector . The initialization of reference variables can, however, cause Garbage Collector to delete the referenced objects.

Note
REFRESH is an obsolete statement used to initialize internal tables.
