<p>PURPOSE: To facilitate the operation by dividing a control program into groups of a functionally hierarchical structure and labelling the control program and groups and displaying labels in accordance with a hierarchical structure on design. CONSTITUTION: When a user selects group 'label display setting (Labels)' and types character 'C', this operation means that he doesn't select 'centering (Center)' under group 'numerical value display setting (Values)' but selects 'centering (Center)' under group 'label display setting (Labels)'. Consequently, the same abbreviation can be assigned to functions in different groups. For example, though functions 'left justification (Left)' and 'long label display (Long Labels)' have character 'L' as the same abbreviation, they are unique in respective groups. All functions can be selected by keyboard abbreviation input. Thus, the operation is facilitated.</p> |
