Section 13,45,5: BUFFERCOUNT

 BUFFERCOUNT = bc

 bc  Is a numeric expression.

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

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

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