SLIP OUTPUT APPARATUS

A disk stores an application program for defining items to be set in a slip image stored/held in a disk and their layout positions. When another slip image similar to this slip image is designated, and part of the slip form is to be modified in accordance with this other slip image, a modification command is input from a keyboard. A definition control section then registers the modification contents in a disk. A modifier section creates a new application program corresponding to the other slip image on the basis of the modification contents in the disk and the definition contents in the disk.
