Using both CREATE_FILE and OPEN_FILE returns error 21.

If you configure the CREATE_FILE, OPEN_FILE, WR_DATA_TO_FILE and CLOSE_FILE to create or open a file on the M340 or M580 data storage SD card,  attempts to perform either a write to the file or close the file without properly considering the usage of the FILEDESC output on both the CREATE_FILE and OPEN_FILE blocks  , will results in an error 21 getting returned..
