Abstract

La présente invention concerne un programme et un procédé d'affichage de documents permettant de différencier visuellement et facilement des informations de liaison. Lorsqu'un document (1) est saisi, des informations de liaison (2a-2c) comprenant des informations de position concernant le document lié et un contenu de notation indiquant la présence de la liaison sont extraites du document (1) saisi (étape S1). Ensuite, des objets (3a-3c) correspondant aux informations de liaison (2a-2c) extraites sont générés (étape S2). De plus, le document (1) est affiché et les objets (3a-3c) générés sont affichés sous forme d'écrans (6a-6c) comprenant un contenu de notation compris dans les informations de liaison correspondantes (étape S3). Lorsque l'un des objets est sélectionné par saisie opérationnelle, le document lié est acquis en fonction des informations de position comprises dans les informations de liaison correspondant à l'objet sélectionné (étape S4).
