CACHENUM=n

n
specifies the number of I/O data-cache pages to be used per SAS file. The default value is 10.

Details

The CACHENUM= data set option operates in conjunction with the CACHESIZ= data set option. Pages are cached in memory in a buffer that is the size of the CACHESIZ= value. The SAS System maintains up to the CACHENUM= value of these caches for each open file.
