Substack ?

[John Cuccio]

I have a substack. rev 1.1

>From the main stack openstack handler I put
on openstack --(from main stack)
open stack "progress"  -- the substack
go to card 1 of stack "main"
end openstack

I put the second line in because I want the main stack to be active. Because
of line 1 the substack is active. This second line does not do it. How do I
make the main stack the active stack.
