ABAP CLEAR WITH NULL Statement syntax, information and example SAP source code

CLEAR - WITH NULL

Short Reference

ABAP Syntax(Obsolete) CLEAR dobj WITH NULL.

What does it do? 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.

Latest notes: 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.
