Abstract
A text document is stored as a sequence of primary records linked by a table. When an operator changes one of the records, the changed text is stored as a secondary record associated with a primary record in the table. If the operator later chooses to undo the changes, the secondary records are deleted. If he chooses to keep the changes, the secondary records are substituted for the associated primary records, and the latter are deleted.
