Close processing for tape

 

When you close a tape device file, the system performs functions according to what you specify in the tape device file.

The system uses the ENDOPT parameter on a CRTTAPF, CHGTAPF, or an OVRTAPF command. The system can perform the following functions:

• The system rewinds the tape.

• The system leaves the tape as it is.

• The system rewinds and unloads the tape to remove it from the magnetic tape device.

If the tape operation ends abnormally:

• The position of the tape when you close the device file might be unchanged.

• The system might rewind the tape regardless of specified program instructions.
