See Also
DBF(), FCOUNT(), FIELD(), FILTER(), FMT(), INDEXEXT(), INDEXORDER(), LEN(), NDX()
Description
The KEY() function is synonymous with the INDEXKEY() function. The KEY() function returns the index key expression for index <expN>, or a null string if no index file exists. When used in conjunction with the INDEXORDER() function, the KEY() function will return the index key expression of the master index. The KEY() function always returns a character string in lower case.
Example
use accounts index acc_no, date_paid ? key(1) acc_no + dtos(date_rec) set order to 2 ? key(indexorder()) dtos(date_paid) + str(amo_paid,11,2) index on lower(left(company,20)) to company ? key(1) lower(left(company,20))
