I want to create a list containing other lists but can't seem to  
figure out how to do it. When I create a new, empty list then try to  
add already-created lists, those lists lose their "listness", i.e.  
their contents just become items in the new list. For example:

set thisList to {1, 2, 3}
set thatList to {"a", "b", "c"}
set bothLists to {}
set bothLists to ((bothLists & thisList) & thatList)

---> {1, 2, 3, "a", "b", "c"}

but I want to get:

---> {{1, 2, 3}, {"a", "b", "c"}}

Can this be done?

Thx for any help,

RJay
