ADD-CORRESPONDING struc1 TO struc2.
Effect
This statement, which is not allowed in classes, adds structures by component. Structures must be specified for struc1 and struc2. All components of the same name in struc1 and struct2 are added in pairs and the result is assigned to the respective component of struct2.
The names are compared, as in the statement MOVE-CORRESPONDING. For each component pair with the same name comp, the statement
ADD struc1-comp TO struc2-comp.
is executed, and the appropriate conversions are performed, if necessary.
Note
This statement is error-prone because, particularly in complex structures, it is not easy to check that components of the same name have the data type and content necessary for a numeric operation.
Example
The components x and y exist in both structures and are added. After the addition, the results are in struc2-x and struc2-y.
DATA: BEGIN OF struc1,
x TYPE i,
y TYPE i,
z TYPE i,
END OF struc1,
BEGIN OF struc2,
a TYPE i,
b TYPE i,
x TYPE p LENGTH 8 DECIMALS 0,
y TYPE p LENGTH 8 DECIMALS 0,
END OF struc2.
