Follow-up Comment #3, bug #24801 (project pspp):
> The cost, at most, would be doubling the memory and disk requirements (for
a single level of undo).
The single level qualification is of course pertinent. I was thinking of
allowing multiple levels.
As I recall, what spss does (did) was to allow multiple levels of undo, until
an EXECUTE happens, at which point the stack is emptied and one cannot undo
anything.
