This function is used to set the test state. The test state can be set to True, False, the toggled value of the test 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.
If a named variable is specified, the name field may contain any of the escape sequences described in Escape Sequences.
When running stepwise, the operation is only performed once.
