## 13.6.6 BUFFERCOUNT Specifier

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

  BUFFERCOUNT = bc
  bc
  Is a scalar numeric expression in the range 1 through 127. If necessary, the value is converted to integer data type before use.

The BLOCKSIZE specifier determines the size of each buffer. For example, if BUFFERCOUNT=3 and BLOCKSIZE=2048, the total number of bytes allocated for buffers is 3*2048, or 6144 bytes.

If you do not specify BUFFERCOUNT or you specify zero for bc, the default is 1.

For More Information:

- On the BLOCKSIZE specifier, see Section 13.6.5.
- On obtaining optimal run-time performance, see your user manual or programmer's guide.
