Mark,

If the processing falls off the bottom of the table it is exactly like 
hitting an END statement.  It is also in where you use the END 
statement.  If it is in the context of an @When something, it will not 
end the table.

It must be in the context of the normal flow of the processing, same as 
input logic.
