System flags are implicitly declared variables. Using the Input Assistant, a variable SystemTaskInfoArr can
be found under system variables. This variable is a field with four structures of type SYTEMTASKINFOTYPE
[}71]. The structure definition can be found in the system library. The index in this field is the task ID.
