To minimally hook up Hypercard to Xanadu with XCMDs, you would
still want to have all the fields on a single card to have a
single version control and permissions control structure.
I suppose we could actually
do that with inclusion lists that use containment, and pay no
attention to the fact that the hierarchical structure of an inclusion
list is overkill for card field organization. We would use the
headline in the inclusion list as the field name, so that the hypercard
user could sort out the individual items to go into the different
fields on the screen.
To actually implement Hypercard-like objects in Xanadu, you would
want all the components (the foreground picture, each text field,
and each button) to fall under the same version control and permissions
control together. You also want to carry a bunch of related information
(like the names of the fields, their sizes and locations, the
scripts, etc) around inside the same bubble.
It's this grouping into a single bubble of many heterogeneous
things, each with lots of record-like attributes, that is different
from anything we've got at the moment.
Ravi, would it be easy to implement hyper-cards in waldos? Please
do not think about this too much; it is definitely postponeable.
