Description
The INDEXKEY() function is synonymous with the KEY() function. The INDEXKEY() function returns the index key expression for the master index or index <expN> if specified. A null string is returned if no such index exists. The INDEXKEY() function always returns a character string in lower case.
Example
use accounts index acc_no, date_paid ? indexkey(1) acc_no + dtos(date_rec) set order to 2 ? indexkey(indexorder()) dtos(date_paid) + str(amo_paid,11,2) index on lower(left(company,20)) tag company ? indexkey() lower(left(company,20))
