'this card of this stack' is an object reference - when evaluated in
contexts which don't expect an object reference, object references
return the *content* of the object, or an error (if the object has no
content)... Only buttons and fields have content - in which case
evaluating them returns the 'text' of the object.
Most things *don't* expect an object reference - places that do are
where an object needs to be acted on, rather than a value being needed.
For example:
set the X of <object-reference>
put exists(<object-reference>)
put there is an <object-reference>
answer <string>
Warmest Regards,
Mark.
