QRG2100

The File-Designation entry (position 16) is not P, S, F, R, or T but the File-Type entry (position 15) is I and the Device-Type entry (positions 40-46) is DISK. File-Designation entry defaults to S.

Change the File-Designation option in position 16, OR the File-Type option in position 15 and the Device-Type option in positions 40-46. Compile again.
