      <p class="para_topic">This sequence has only one marker, the start of program. This window allows you to determine which blocks the system outputs when this event occurs in the tool path. It is important to note that the start of program event occurs before any other event is handled. Any UDE (User Defined Event) data is only available after the Start of Program Event.</p>
      <p class="para_topic">Note that the Start of Program and End of Program events are only output once by the main post of linked post. &nbsp;If you overwrite either of these event handlers, the linked post reinstates the original Start of Program and End of Program.</p>
