This property applies to paged list boxes only. It determines whether the case of the data items will be considered as the user searches for a data item. It can take one of four values:
| 0 | PL-SORT-DEFAULT | Use the default sort order. (Same as value 3.) |
| 1 | PL-SORT-NONE | Every character the user types results in a notification to the COBOL program. |
| 2 | PL-SORT-NATIVE | The paged list is searched and case is considered. If the item that the user has entered is on the current page, it is selected. |
| 3 | PL-SORT-NATIVE-IGNORE-CASE | The paged list is searched and case is not considered. If the item that the user has entered is on the current page, it is selected. |
