!Description:   
            Routine in Validation group of the Level-1A geolocation
                software to find the next unflagged sample in a flag array.
 
!Input Parameters:
                int sample_flags [] - array of flags for data samples
        int number_of_samples - array size
        int start_sample - start index for search
 
!Output Parameters:
 
Return parameter:
                int - index of next unflagged value if found, or
          FAIL if end of array reached.
 
Global variables:
        None
 
Call functions:
        None
