Description

The TAG() function returns the tag name of the specified .dbx file, or the filename of a single (.ndx) file. With no parameters, the TAG() function operates in the current workarea on the master index. If the optional <.dbx filename> is not specified, one of its tags must be the master index order for its tag names to be queried. If no indexes are active or the specified index is not active, TAG() will return a null string. An error will be given if an invalid alias name is given.
