-BUFSIZE n | nK | nM | MAX | MIN

n | nK | nM: specifies the buffer size in multiples of 1; 1,024 (kilobytes); and 1,048,576 (megabytes), respectively. For example, a value of 8 specifies 8 bytes and a value of 3M specifies 3,145,728 bytes.

MIN: specifies the buffer size to be 512 bytes.

Details

The BUFSIZE system option allows you to specify the permanent buffer size for SAS files.

Under Windows, the value can range from 512 bytes to 16 megabytes. A value of 0 enables the engine to pick a value depending on the size of the observation.

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.
