When a user is inserting text into a document that has already been paginated, no text should be lost if the user inserts more text than a page can hold.
Additional Information:
It is difficult for a user to keep track of page size, particularly if the size of the display screen is less than the full page specified for printed text. A user will often not know when more text has been inserted than will fit into a page. The computer should accommodate text insertions with automatic repagination.
