■Converting and writing data in CSV format
• If the extension is omitted, the extension will be ".CSV".
• When an existing file is specified, the following occurs.
• When a value other than FFFFFFFFH is specified in (d1)+4 or (d1)+5, data is saved to the file after deleting the existing data in the file.
• When a value other than FFFFFFFFH is specified in (d1)+4 or (d1)+5, data is added and saved to the end of the file.
• If a file that does not exist is specified, it will be created and data will be saved to the beginning of the file. The newly
created file has the archive attribute.
• If the media runs out of free space during additional saving of data, an error occurs. In this case, the data already added
and saved successfully is held as is and as much remaining data as possible is added and saved before termination with
an error.
• When the number of columns is set to 0, data is read as a single-row data in a CSV format file.
Ex.
The number of columns is set to 0 when writing data after conversion to the CSV format.
