Defer write (DFRWRT)

Specifies that the writing of data is delayed until it is written out with other data when a read request is made. Control is returned to the program immediately after the data is received.

The possible values are:

*YES
When the program issues a write request, control is returned after the buffer is processed. This may result in improved performance.

*NO
After a write operation, the user program does not regain control until the input/output is completed.

*CMDDFT
The system default is used.
