Syntax
... 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
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.
