 Name       : HCPAFFBK
 Description: AFFinity management control BlocK
 DSECT      : AFFBK
 Function   : The AFFBK maps the storage in HCPRCC starting at
              label HCPRCCAF, extending for the length of this
              block.  When the AFFBK is copied via the 'COPY'
              psuedo-op into any module other than HCPRCC, it will
              generate a DSECT.  When copied in HCPRCC, however,
              it will generate code to actually define the fields.
              The AFFBK is used by the processor feature affinity
              management routines as an area to do bookkeeping
              and recording.
 Located by : HCPRCCAF is the address of the start of the block.
 Created by : The block is DCed in module HCPRCC.
 Deleted by : Never deleted
 Serialized : Alterations and references to the AFFBK are
              serialized by the Scheduler Lock.
