Hierarchically structured data unit operating system for structure editor of programming language, has displaying device to display data unit in field of table, where display position of unit is dependent on hierarchical position of unit

摘要

The system has a data unit- displaying device for displaying a data unit (15) in a field (13) of a table (11), where a display position (14) of the data unit in the field is dependent on a hierarchical position of the data unit. The device displays a navigation unit and attributes in respective fields of the table. The hierarchical position is dependent on generating commands used for manufacturing the data unit. Independent claims are also included for the following: (1) a method for operating a hierarchically structured data unit (2) a computer program product for operating a hierarchically structured data unit.
