FRXAN Prolog

 Name       : HCPFRXAN
 Description: Fast-fit anchor
 DSECT      : FRXAN
 FUNCTION   :
              Maps the anchor block for the fast-fit tree
              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.
 NOTES      : This block contains the address and length of the
              fast-fit memory pool, together with the address and
              length of the "root" node within the pool. See the
              prologue of HCPFRX for a more detailed description.
