This statement is used to set the action test state or per file test states. The state can be set to True, False, the toggled value of the state, or to the contents of a specified Variable or Named Variable. When setting to the contents of a track or named variable, the state is set to False if the contents of the variable cannot be converted to a non zero integer, otherwise the state is set to True. Case insensitive true is also accepted.
If a named variable is specified, the name field may contain any of the escape sequences described in Escape Sequences.
