BUFNO=n | nK | hexX | MIN | MAX

n | nK

specifies the number of buffers in multiples of 1 (bytes); 1,024 (kilobytes). For example, a value of 8 specifies 8 buffers, and a value of 1k specifies 1024 buffers.


specifies the number of buffers as a hexadecimal value. You must specify the value beginning with a number (0-9), followed by hexadecimal characters (0-9, A-F), and then followed by an X. For example the value 2dx specifies 45 buffers.


sets the minimum number of buffers to 0, which causes SAS to use the minimum optimal value for the operating environment.


sets the number of buffers to the maximum possible number in your operating environment, up to the largest four-byte signed integer, which is 231-1, or approximately 2 billion.


The buffer number is not a permanent attribute of the data set; it is valid only for the current SAS step. BUFNO= applies to SAS data sets that are opened for input, output, or update.
