Where the string "failed" is created in steps in the main sequence to fill into Parameter.Result PostUUT in the NI teststand II courese example 4-1 Modifying callback.seq

Question

For PostUUT in  the NI teststand II  courese example 4-1 Modifying callback.seq, there are two steps, one is Test Passed,
the other is Test Failed, both set each preconditions, for example, Parameters.Result.Status == "Failed"  in the test failed step, if the step failed in the main sequence,the string "failed " is filled into Parameters.Result.Status
 but I can't find where the string "failed" is created in steps in the main sequence. 
 Because I can't find any expression in any steps  to fill into Parameters.Result of  the test failed step in the PostUUT. 
In fact, when running if step fails, the string "failed " is filled into Parameters.Result.Status 
 Would you please  explain for it ? 
thanks,

Hi,
Look at the Sequential Model Sequence File, and either the sequence SinglePass of Test UUTs for the step that invokes the step Post UUT.
Then look at the Parameter List for the SequenceCall for that step. you will find your answer.
