 Ciao,

Hello;

The Siemens forum has decided to use English as an international language, to facilitate exchanges between participants from many countries. Please write to us in English on your next visit.

Open the picture attached with the first post in this thread. Notice the "pointer" variable in the function parameters (above the code window), inside the Input section? Look further in the list of patameters, you will find a section for input/output parameters, this is where the pointer variable should have been assigned

Hope this helps.
