Terry, Definitely use substacks to modularize your code, BUT, I would suggest you do just a wee bit of reading on the message path, because it's important for everyone, and all of the questions you asked are discussed there: 1) In the LC toolbar at the top, the second-to right button is "Resources". Click it 2) The second link down is the "User Guide". Click it 3) Inside there search for "message path". There is a whole discussion of what it is and how to use it. 4) SEND and PASS and START USING STACK are your friends.

This is probably fine.
