Function OrdDestroy() Foundation
Deletes one or more indexes
OrdDestroy( [<cTagName>|<nIndex>] ) --> NIL
The return value of OrdDestroy() is always NIL.
The index function OrdDestroy() deletes the index (tag) <cTagName> from an index file (bag) containing one or more indexes. In case the index file has just one index, the function also destroys the index file.
The function operates on the indexes of the current work area. If no <cTagName> or <nIndex> is passed, all indexes of the current work area are destroyed.
In case of compound indexes, trying to delete the first index yields a runtime error. Since the removal of the first index always leads to the destruction of the index file, all other indexes must first be destroyed before destroying the first index.
