Note FREAD(700) will not be able to read the last byte in a file that has been written to the Memory Card if the file contains an odd number of bytes. Add 00 hexa- decimal to the end of the file if necessary to write an even number of bytes to the Memory Card.

Note The UM and DM Areas contain binary data. Set the data type to binary using the type command before reading or writing files using FTP.

Note For details on how to use File Memory Instructions, refer to the CS/CJ Series Instructions Reference Manual (W340).
