Syntax

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

n | nK | nM | nG: specifies the buffer size 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 0. The minimum number is -2147483648.
MAX: sets the number of buffers to the largest signed, 4-byte integer representable in your operating environment. Under OpenVMS, the maximum number is +2147483647 or 2 gigabytes.
hexX: specifies the number of buffers as a hexadecimal number. This number must be followed by an X, as in hexadecimal-valueX.

Details

The BUFSIZE= system option specifies the permanent buffer size for output SAS data sets. Under OpenVMS, the size of the buffer can range from 0 to 2,147,483,647 (2 gigabytes). The value is always rounded up to the next multiple of 512 bytes. If the value is 0, the engine picks a value depending on the size of the observation. The default value is 0. The value of BUFSIZE is saved with the data set and be viewed with PROC CONTENTS or a similar window.

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

Comparisons

The BUFSIZE= system option can be overridden by the BUFSIZE data set option.
