Wrong open mode or access mode for write (Recoverable) -You have tried to write to a file in sequential access mode that you have not opened for OUTPUT or EXTEND, or you have tried to write to a file in random or dynamic access mode that has not been opened INPUT or I-O, or which is not open at all. -Close the file and reopen it with the correct open mode for the file type.
