Bit value:  64

This opcode is used to close a memo file opened with opcode MMO'OPN, and should be used prior to exiting a program. Although no disk updating will be performed on the close operation (since disk buffers are always flushed after each update), this is still a good idea to cleanly exit from the LOKSER database. (Do not use this opcode unless you opened the file with the MMO'OPN opcode.)
