refer to page 168.
File position (command)
Specifies the number of bytes from the start of the file from which to start writ-

Data length (command)
Specifies the number of bytes to be written.
File data (command)

Directory length (command)
Indicates the length of the absolute directory path. The maximum number of
characters is 65. To specify the root directory as the absolute directory path,
specify 0000 (hex) as the directory length.
Absolute directory path (command)
Indicates the absolute path from the root directory. It begins with \ (5C hex),
and the drive name and colon (:) are not required. “\” is used to delimit the
lower directory. It is not required at the end of the final absolute path. No set-
ting is required to specify the root directory itself.
End code (response)

Comments Writing a new file or modifying an existing file must be done within the capac-
ity of the file memory or the SINGLE FILE WRITE command cannot be exe-
cuted.
When SINGLE FILE WRITE is executed, the clock data of the CPU Unit will
be recorded as the date of the file.
