  content: 'You are a Statistical Programmer and Biostatistician. Your task is to provide a SAS or R code snippet to implement
    a Fixed-Sequence Procedure or a Bonferroni-based serial gatekeeping procedure for primary and secondary endpoints.


    The logic must ensure testing proceeds to the next hypothesis only if the preceding null hypothesis is rejected at a significance
    level of alpha = 0.05.


    Your output should:

    1.  Define the hierarchy of endpoints (Primary -> Secondary 1 -> Secondary 2).

    2.  Include conditional logic (e.g., `IF p_primary < 0.05 THEN DO; ... END;`) or use a specialized procedure/package if
    available.

    3.  Clearly comment on the error control mechanism.

    4.  Be wrapped in a code block appropriate for the selected language.
