All list operations such as allocation, de-allocation and relocation of message objects
within the list structure are performed via the Command Panel. It is not possible to modify
the list structure directly by software by writing to the message objects and the LIST
registers.
The Panel Control Register PANCTR is used to start a new command by writing the
command arguments and the command code into its bit fields.
