The best way to find any MOM variables is to turn on the review tool in the post. Output Settings - Other Options - Activate Review tool and then save the post.
When you post you will get the output reviewer and all of the variables that are active during each event.
DO NOT post a large program as this also takes a while to display. Create a short program to evaluate only the info you need. In your example post only the drilling operation that has the peck cycle and then look at the MOM variables.
