BUFNO=n | nK | nM | nG | MIN | MAX | hexX

n | nK | nM | nG: specifies the number of buffers that you want to allocate in bytes (n), kilobytes (nK), megabytes (nM), or gigabytes (nG).
MIN: sets the number of buffers to 0, and requires SAS to use a default value. Under OpenVMS, the default value is 1.
MAX: sets the number of buffers to the largest signed, 4-byte integer representable in your operating environment. Under OpenVMS, the maximum number is usually 10.
hexX: specifies the number of buffers as a hexadecimal number. This number must be followed by an X, as in hexadecimal-valueX.

Details

Under OpenVMS, there is no maximum number of buffers you can allocate, except for memory constraints. However, it is unusual to specify more than 10.

You may want to vary the value of the BUFNO= system option if you are trying to maximize memory usage or the number of observations per page.
