Abstract
Abstract Objects are capsuled in an object-oriented computer system by combining instance object sensors and method object sensors previously prepared and stored in a secondary memory (3). An element file (2) contains records including a record identifier and at least one of an attribute identifying at least one method and a command identifying an instance. Representations of the records in the element file (2) are displayed on a display screen (1) and a pair of records, one including a command and another including an attribute, are selected by a user to be combined into an object capsule. The object capsule is stored in an object file (6) for subsequent selection for execution. When an object capsule is selected for execution, the attribute and command stored therein are used to identify at least one method and an instance of data to be swapped into primary memory (8) from method and instance files (5, 4) in the secondary memory (3). A processor then executes the method to operate on the data which have been swapped into the primary memory (8) together.
