Retrieve the current execution call chain

Automatically translated from English

When programming an application, you may need to know where you are in your code, especially when one method calls other methods, which may then call other methods. That’s why it’s very helpful to see the chain of methods, or the call chain, during the debugging process. For this, 4D v17 R6 provides the new Get call chain command to give you an insight into the executed code. Now you won’t have to worry about getting lost anymore!
