ABSTRACT:
A method is disclosed for place value assignment for sortable keys in a National Language Support (NLS) data processing system. Each sortable key within the data processing system is assigned an alphabetic key value, a diacritic key value, a case key value and a special character key value. After building these key values for each key within the system, a place value may be assigned to each unique character which is based upon these four values. In one embodiment of the present invention, each character or key has a fixed length place value data frame associated therewith, with selected subsets of that data frame associated with each key value. This embodiment may require selected key values to be "padded" to fully occupy the designated subset within the fixed length place value data frame; however, the increased memory requirement which this approach requires will be offset by the ease of diagnosis and manipulation which this approach permits.
