Close processing for tape

Find out what happens to your tape when you close a tape file.

When you close a tape device file, the system performs one of several 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.
