There is no handler after the "go" command. A single handler in the mainstack navigates to the substack and then continues, in-line, to do things on that subStack.
The stack and card scripts of the substack are empty.
This works fine if the subStack has already been opened, but fails if not. So in a new session, I have to run the handler, which opens the substack and then "quits", and then run it again, where it then does its thing.
This works just fine, that is, running the handler twice. This is not the way I understood life was all about.
I tried to get the result, but this fails, of course, because of the issue itself:
The line after the "go" never fires, because the handler has quit.
Unless the substack is already open, as I said, and in that case the result is empty, as it should be.
I know of no way to place all the substacks in memory upon initial opening of the mainstack, apart from "going" to those stacks. I could just not know how to do that of course, and that would solve my problem, though not explain my problem.
