If the record is locked, UniData displays the message “THE RECORD IS ALREADY LOCKED”. 1-666 UniBasic Commands Reference record.ID.expr Specifies a record to lock. ON ERROR statements RECORDLOCKL CLIENT.FILE,"Smith" LOCKED PRINT "THE RECORD IS ALREADY LOCKED" Related Commands UniBasic Specifies statements to execute if the RECORDLOCKL statement fails with a fatal error because the file is not open, an I/O error occurs, or UniData cannot find the file.
