Concatenate 2 strings in ABAP without using CONCATENATE function

In ABAP you can use && sign to concatenate variables as below ?

Variable Declaration and Assignment

First, declare the variables and assign values to them ?

DATA: hello TYPE string,
      world TYPE string,
      helloworld TYPE string.

hello = 'hello'.
world = 'world'.
helloworld = hello && world.

The output of the above code is ?

helloworld

Direct String Concatenation

If you want to concatenate strings directly without using variables, you can use ?

helloworld = 'hello' && 'world'.

The output of the above code is ?

helloworld

Adding Spaces Between Strings

If you want to keep space in between concatenated strings, you would require backtick symbol (`) to define string literals as below ?

helloworld = hello && ` and ` && world.

The output of the above code is ?

hello and world

Conclusion

The && operator provides a simple and efficient way to concatenate strings in ABAP without using the CONCATENATE function, and backticks allow you to include spaces and special characters in your concatenated results.
