Description
The EXCLUSIVE() function returns .F. if the table open in the currently selected workarea is available for shared access, and .T. if it is open for private use. If the optional <workarea | alias> is specified, the function will operate in the specified location. The MODIFY STRUCTURE, PACK, REINDEX, INDEX ON <exp> TAG and ZAP are the only commands that require exclusive use of the table. For reasons of safety, the INDEX ON ...TO <.ndx> command should also be used only with exclusive use of the table.
