I am using a stacked sequence structure. Within one sequence, if I find a condition is met, I want exit the whole sequence structure without executing following sequences. Is there a simple way to do this? Thanks a lot.
Simple is a relative term. I would highly recommend not using sequence structures as, usually, it can hide code (stacked) and the same can be accomplished using data flow. If you cant get around using it (or just dont want to) then the below would be one obvious solution...
You cannot exit a sequence structure, stacked or flat. Every sequence must execute. You could use case statements as shown by Chaos to skip code in the succeeding sequence frames. The best option is to use a state machine. You can cause an exit at any time without having to create special case structures just to skip code. Search for examples on state machines. If you can't find one, I may have a template somewhere that I can dig up.
