Syntax

-BUFSIZE n | nK | nM | nG | hexX | MAX

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

n | nK | nM | nG: specifies the buffer page size in multiples of 1 (bytes); 1,024 (kilobytes); 1,048,576 (megabytes); or 1,073,741,824 (gigabytes). You can specify decimal values for the number of kilobytes, megabytes, or gigabytes. For example, a value of 8 specifies 8 bytes, a value of .782k specifies 801 bytes, and a value of 3m specifies 3,145,728 bytes.
hexX: specifies the buffer page size 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, 2dx sets the buffer page size to 45 bytes.
MAX: sets the buffer page size to 2,147,483,647.

Details

The buffer page size can range from 1K to 2G-1.

If you specify a nonzero value when you create a SAS data set, the BASE engine uses that value. If that value cannot hold at least one observation or is not a multiple of 1K, the engine rounds the value up to a multiple of 1K.
