BUFNO=number-of-buffers

number-of-buffers: specifies a value from 1 to the maximum number of buffers, technically 2,147,483,647 in the CMS environment. The practical limit is lower, depending on the size of the buffer and the virtual machine.

Details

The buffer number is not a permanent attribute of the data set and is valid only for the current SAS session or job.

To reduce input/output operations on a small data set and speed up execution time, allocate one buffer for each memory page of data to be processed. This technique is most effective if you read the same observations several times during processing.
