Use complex variables
18528
There are different complex variables (STRUCT) at the programmer's disposal. They bundle logically
associated data sets. Thereby, they facilitate the organisation of the data storage in the application
and at the same time reduce the error rate when variables are declared.
The following complex variables are available:
Name
