FREE - Reset to correct initial value for type,
including release of resources
Basic form
FREE f.
Effect
Like CLEAR f , FREE
f resets any data object f to
the correct initial value for its type.
In contrast to CLEAR , however, FREE also releases any
resources connected with the data object f . This may be relevant
with internal tables, structures with tabular components as well as
table work areas (created with
TABLES ).
After FREE f , you can address the data object f again at
any time, but this may involve reallocating resources.
Note
If f is an internal table with a header line, the
FREE f statement refers to the table body, but the CLEAR
f statement refers to the header line.
Note
Performance
The runtime required to execute the FREE statement is about 5
msn (standardized microseconds).
