FUNCTION = This DSECT describes the task subpool statistics
provided by the storage manager.
It is provided for use in users monitoring applications
to map the statistics returned via the statistics exit
or SMF.
An instance of this data area may represent the
statistics for either the task subpools above the 16 meg
line or those below the 16 meg line.
There is a single instance of this data block.
LIFETIME = This data block is created by the storage manager to
hold task subpool statistics. It is released when the
request for statistics has been satisfied.
LOCATION = Caller is passed a pointer to the head of the block.
INNER CONTROL BLOCKS = None
NOTES :
DEPENDENCIES = S/370
RESTRICTIONS = none
MODULE TYPE = Control block definition
