Thanks Shane for your reply. As a matter of fact, I'm going to choose the first option you mentionned hereby since I think it's the best option. Nice of you to have answered

By pressing a button linked to the case statement, the calculations for the remaining iterations can basically be skipped. The current iteration will still execute to completion though..... Hope this helps Shane.
