 NAME       : HCPFRXAN
 DESCRIPTION: Storage pool statistics
 DSECT      : FRXAN
 FUNCTION   :
              Maps the storage pool statistics for the storage
              pools maintained by HCPFRX.
 CREATED BY : N/A (statically defined within HCPFRX)
 DELETED BY : N/A
 SERIALIZED :
              All HCPFRX data areas, including this anchor block,
              are serialised by TSGET on the flag HCPFRXLK.
 RELOCATION CONSIDERATIONS : None
 NOTES      : This block maps the address and length of the
              fast-fit memory pool, the address and length of the
              "root" node and statistics.  It can be used to map
              the HCPFRXFP (primary pool) and HCPFRXFS (secondary
              pool) information.  See the prologue of HCPFRX
              for a more detailed description.
