The BUFFERCOUNT keyword specifies the number of buffers to be associated with the logical unit for multibuffered I/O. It takes the following form:

BUFFERCOUNT = bc

bc

Is a numeric expression.

The range of values for bc is from 1 to 127.

Note

On OpenVMS systems, BLOCKSIZE keyword determines the size of each buffer. So, if BUFFERCOUNT=3 and BLOCKSIZE=2048, the total number of bytes allocated for buffers is 3*2048, or 6144.
