Operators
ABAP contains the following operators:
- Operators that perform special operations in operand positions:
- Declaration operators
The declaration operators DATA and FIELD-SYMBOL declare variables or field symbols in operand positions.
- Constructor operators
The constructor operators NEW, VALUE, REF,
EXACT, CONV, and CAST construct values for data objects of certain data types in constructor expressions.
- Operators that join multiple operands in a single expression:
- Assignment operators
The assignment operator = joins the source field and target field of an assignment. In the case of assignments, the special
casting operator ?= performs a
down
cast. The operator = also joins actual parameters with formal parameters, for example in procedure calls or when working with
data clusters.
- Arithmetic operators
The arithmetic operators +, -, *,
/, DIV, MOD, and
** join two or more numeric operands with an arithmetic expression. In addition, the characters + and - act as plus/minus signs in arithmetic expressions.
- Bit operators
The bit
operators BIT-AND, BIT-OR, and BIT-XOR
join two or more byte-like operands with a bit expression. The bit operator BIT-NOT negates a byte-like operand.
- String operators
The
string operator && chains two character-like operands to a string expression.
- Relational operators
Relational operators occur in relational expressions, which themselves are components of logical expressions. The
comparison operators
=, <>, <,
>, <=,>=, BETWEEN,
and so on join two or more operands of any data type as a comparison expression. There are additional relational operators for specific data types. The
predicate operator IS qualifies an operand.
- Boolean operators
The
Boolean operators AND, OR, and EQUIV
join the results of individual logical expressions with a logical expression. The result of a logical
expression is either true or false. The Boolean operator NOT negates the result of a logical expression.
- Operator that joins two operands in compilations:
- Literal operator
The
literal operator & joins two literals or two string templates with a literal or a string template.
