log_exp - EQUIV
Syntax
ABAP_KEY ... log_exp1 EQUIV log_exp2 ...
Effect
Joining two logical expressions log_exp with
EQUIV produces a new logical expression which is true if both
expressions are true or both expressions are false. If one of the
expressions is true and the other one is false, the join is false.
Within a bracketing level , only two logical
expressions can be joined using EQUIV .
Notes
The operator EQUIV has a weaker join effect than NOT ,
AND , and OR .
The operator EQUIV implements an equivalence join. Negating a
join like this using NOT corresponds to an
XOR join ( eXclusive OR ). It is true if one of the
expressions is true and the other one is false.
Example
The condition in the IF statement is true if o1 , o2
and o3 , o4 are pair-wise either both equal or both
unequal.
DATA: o1 TYPE i,
o2 TYPE i,
o3 TYPE i,
o4 TYPE i.
...
IF o1 = o2 EQUIV o3 = o4.
...
ENDIF.
