## Assigning Values
|
||||
|
||||
- When you declare character-like data objects, you can specify start values directly with the `VALUE` addition, e.g. `DATA chars TYPE c LENGTH 3 VALUE 'abc'.`.
|
||||
- You can do value assignments to data objects using the the [assignment operator](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenassignment_operator_glosry.htm "Glossary Entry") `=`.
|
||||
- Various ABAP statements assign values. You can do value assignments to data objects using the [assignment operator](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenassignment_operator_glosry.htm "Glossary Entry") `=`.
|
||||
- As mentioned above, you can declare character-like data objects inline using the operators `DATA` or `FINAL`.
|
||||
- You can use the operators at many [write positions](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenwrite_position_glosry.htm "Glossary Entry").
|
||||
- Unlike the `VALUE` addition of the declaration statements, inline declarations allow you to declare variables for the results of expressions or at other positions where character strings are returned.

### Literal Operator
|
||||
|
||||
The [literal operator](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenliteral_operator_glosry.htm "Glossary Entry") `&` combines [text string literals](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abentext_string_literal_glosry.htm "Glossary Entry"), however, with [significant differences](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenliteral_operator.htm) to `&&`, which the code snippet demonstrates.

### Byte String Processing

## Determining the Length of Xstrings
|
||||
|
||||
The built-in function [`xstrlen`](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abendescriptive_functions_binary.htm) returns the number of bytes of a byte-like argument.
|
