constructor Create(
    AClient: TIdCmdTCPClient
); reintroduce;

Create is the reintroduced constructor for the object instance. 

Create calls the Create constructor indicating that the thread is not created in a suspended state and uses an inner loop during thread execution. 

Create initializes the Context member variable for the listening thread, and assigns the value in AClient to the Client property. 

Create sets FreeOnTerminate to False prior to exiting from the method.
