rel_exp - Binary Relational Operators
The following table shows the binary relational operators for
comparisons between two operands (data objects or return values or
calculation expressions ) of
any data types in comparison
expressions .
operator Meaning
ABAP_KEY = , ABAP_KEY EQ Equal : True if the
value of operand1 matches the value of operand2 .
ABAP_KEY , ABAP_KEY NE Not Equal : True
if the value of operand1 does not match the value of operand2
.
ABAP_KEY , ABAP_KEY LT Less Than : True
if the value of operand1 is less than the value of operand2
.
ABAP_KEY , ABAP_KEY GT Greater Than : True if
the value of operand1 is greater than the value of operand2
.
ABAP_KEY = , ABAP_KEY LE Less Equal :
True if the value of operand1 is less than or equal to the value
of operand2 .
ABAP_KEY = , ABAP_KEY GE Greater Equal : True
if the value of operand1 is greater than or equal to the value of
operand2 .
The values are compared in accordance with the
comparison rules .

Notes
The operators = , , , ,
= , and = are equivalent to EQ , NE ,
LT , GT , LE , and GE respectively. We recommend
that you use only one of these types of operator within a program. If in
doubt, the operators with characters = , , and
are considered to be more up to date, however they also overload
these characters. Relational operators that consist of two letters, on
the other hand, are better suited to other relational operators such as
CO , CN
, and so on that have no alternative forms.
Due to the comparison rules , the size
comparisons shown here are not suitable for determining the textual
order of character-like data objects.
The obsolete forms , =
, and = may still appear outside of classes.
