FUNCTION =
This data area contains global statistics provided by the
Dispatcher Domain on MVS TCBs.
It is provided for use in users monitoring applications
to map the statistics returned via the APi or the statistics
exit.
There is a single instance of this data block.
LIFETIME =
This data block is created by the Dispatcher to store
statistics to be passed to the user in response to a request
for statistics. The storage is released when the user task
is detached.
The DSECT also maps the contents of part of the SMF buffer
created by the statistics domain and is used in the
statistics exit.

LOCATION =
The user is passed a pointer to the head of the storage
block.
