Latest notes:The program DEMO_EXPRESSIONS shows examples of the logical expressions in Release 7.0, EhP2.
ABAP_MODIFICATION_1 Boolean Functions
The new predefined Boolean functions boolc and boolx accept logical expressions as arguments and return their truth values in the form of character strings or byte strings.
ABAP_MODIFICATION_2 Predicate Functions
The new predicate functions return logical values and can be used like relational expressions. Predicate functions for character-like arguments were introduced in Release 7.0, EhP2.
ABAP_MODIFICATION_3 New Boolean Operator EQUIV
The new Boolean operator EQUIV enables an equivalence relationship between two logical expressions.
