Description

The INDEXORDER() function returns the currently selected master index number as specified with the SET ORDER TO command. If no index files are selected, it returns -1. If index file are open, and SET ORDER has been set to 0, the INDEXORDER() function returns 0. If the optional <workarea | alias> is specified, then the function will operate in that <workarea | alias>. When used in conjunction with the NDX() or INDEXKEY() functions, the INDEXORDER() function will return the index file name or index key of the master index. The INDEXORDER() function is synonymous with the ORDER() function.
