Explanation

To produce the output with 'Asthma' (value 1) appearing before 'No Asthma' (value 0), you need ORDER=FORMATTED to sort by the formatted values alphabetically. The WEIGHT COUNT statement is essential because the dataset has multiple rows per observation with a count variable. The NOCUM option suppresses cumulative statistics. Without ORDER=FORMATTED, the default internal ordering would show No Asthma (0) before Asthma (1).
