BLKSIZE=block-size

block-size: can range from 0 to 65,536 bytes.

The BLKSIZE= data set option specifies the blocking factor that is used for input and update of SAS data sets (input only for the V5 engine). When blocking is in effect, SAS is able to read and write multiple data pages by buffering its input and output. When processing a SAS data set, the BLKSIZE= option has no effect unless SAS can place at least four data set pages within the buffer that is specified by the BLKSIZE= option. The BLKSIZE= option does not become an attribute of the data set. Thus, the BLKSIZE= option can be specified for data set input and output.
