Close index files in the current workarea
The CLOSE INDEX command closes index files in the currently selected workarea. All single indexes and non-production multiple indexes will be closed. If the active table has a production index, that is a multiple index with the same basename as the table, the production index will remain open. Production indexes can be detached from their associated tables using the USE <table> NODBX command.
