Using File Memory Section 11-7
Example: Data format using words delimited by commas with CRs after every
10 fields.
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. (Refer to type
on page 311.)
Note For details on how to use File Memory Instructions, refer to the CS/CJ Series
Instructions Reference Manual (W340).
