ABAP is a programming language developed by SAP for programming business applications in the SAP environment.
Previously only procedural, ABAP is now also an object-oriented language thanks to the ABAP Objects enhancement.
PROGRAM zhello_world. START-OF-SELECTION. WRITE 'Hello, World!'.
Instead of printing to the console, ABAP writes values to a list which will be displayed as soon as the main logic was executed.
