BUFSP

The BUFSP parameter specifies the size, in bytes, of an area for data and index buffers. This size is put in the BUFSP parameter of the ACB for each cluster or alternate index being restored or compared.

Operand	Explanation
n	The size, in bytes, of an area for data and index buffers. n must be large enough for at least two data buffers and one index buffer.

Usage Rule

The following usage rules apply to the BUFSP parameter:

VSAM data and index buffers are above the 16M line.
The default is BUFSP=0 unless the GVPARMS utility is used to change it.
When BUFSP is zero, the default is the larger of either the size in the catalog or the size determined from the values specified for BUFND and BUFNI. If BUFSP is coded but is less than the BUFND and BUFNI requirements, n is changed to conform to their requirements.
