### Using the NEW Operator
Using the instance operator [`NEW`](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenconstructor_expression_new.htm), you can create [anonymous data objects](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenanonymous_data_object_glosry.htm "Glossary Entry"), such as anonymous structures. You can access the components or the entire data objects by [dereferencing](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abendereferencing_operat_glosry.htm). For more information, refer to the [Dynamic Programming](06_Dynamic_Programming.md) and [Constructor Expressions](05_Constructor_Expressions.md) cheat sheets.

"Creating a data reference variable

"Populating the anonymous structure
addr_ref1 = NEW #( name = `Mr. Duncan Pea`
street = `Vegetable Lane 11`
city = `349875 Botanica` ).
addr_ref1->name = `Mrs. Jane Doe`.

### Using the CORRESPONDING Operator and MOVE-CORRESPONDING Statements
- You can use statements with [`MOVE-CORRESPONDING`](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abapmove-corresponding.htm)
