CLEAR - WITH NULL
Other versions: 7.31 | 7.40 | 7.54
Obsolete Syntax
CLEAR dobj WITH NULL.
Effect
This variant of the statement CLEAR
,
which is not allowed in ABAP Objects, replaces all bytes in dobj
with the value hexadecimal 0. In this case, the data object dobj
must be flat.
Note
The addition WITH NULL
should only be used for byte-like data objects and
should therefore be replaced by the addition CLEAR WITH val
, which offers a higher degree of security in this context.
Bad Example
CLEAR f WITH NULL.
Good Example
CONSTANTS hex TYPE x LENGTH VALUE IS INITIAL.
CLEAR f WITH hex.
