CACHESIZE=n | nK | hexX | MIN | MAX

n | nK

specifies the cache size in multiples of 1 (bytes) or 1,024 (kilobytes). You can specify decimal values for the number of kilobytes. For example, a value of 8 specifies 8 bytes, a value of .782k specifies 801 bytes, and a value of 3k specifies 3,072 bytes.

Range:

0 - 130,048

hexX

specifies the cache 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, the value 2dx sets the cache size to 45 bytes.

MIN

sets the cache size to 0.

MAX

sets the cache size for your operating environment to 130,048.

Details

Pages of SAS files are cached in memory with each cache containing multiple pages. The CACHESIZE= system option controls the size (in bytes) of this data cache.
