specifies the number of extra page buffers in multiples of 1 (bytes); 1,024 (kilobytes); 1,048,576 (megabytes; 1,073,741,824 (gigabytes); or 1,099,511,627,776 (terabytes). For example, a value of 8 specifies 8 bytes, and a value of 3m specifies 3,145,728 bytes.
specifies the number of extra page buffers as a hexadecimal number. You must specify the value beginning with a number (0-9), followed by an X. For example, the value 0ax sets the number of extra page buffers to 10 buffers.

The CBUFNO= option is similar to the BUFNO= option that is used for SAS data set processing.
Increasing the value for the CBUFNO= option might result in fewer I/O operations when your application reads very large objects from catalogs. Increasing this value also comes with the normal tradeoff between performance and memory usage. If memory is a serious constraint for your system, you should not increase the value of the CBUFNO= option. Do not increase the value of the CBUFNO= option if you have increased the value of the CATCACHE= option.
Operating Environment Information: The syntax that is shown here applies to the OPTIONS statement. On the command line or in a configuration file, the syntax is specific to your operating environment. For more information, see the SAS documentation for your operating environment.
