FUNCTION = This data block describes the LSR Pool Statistics
for a specified LSR Pool and totals for all pools.
The data described here is placed in storage by DFHAPST.
This DSECT is also used by DFHSTUP and user programs to
to map the statistics block.
LIFETIME = The storage area is created when a request for AP
domain File Control statistics is received. It is
released when the caller has acknowledged receipt of
the data.
LOCATION = The caller is passed a pointer to the head of the block.

The following DSECT is repeated for each buffer size in the pool.
If separate index and data buffers are NOT being used, there will
be A08NBS repeats of this DSECT, one for each buffer. If
separate data and index buffers are being used (A08IDSEP flag set)
there will be A08NBS 2 repeats of this DSECT (A08NBS for the data
buffers followed by A08NBS for the index buffers).
