The File-Designation entry (position 16) is not P, S, or F but the File-Type entry (position 15) is U and the Device-Type entry (positions 40-46) is DISK. File-Designation defaults to S.
Change the File-Designation option (position 16), OR the File-Type option (position 15) and the Device-Type option (positions 40-46). Compile again.
