     NAME       : HCPSRBBK
     DESCRIPTION: Symptom Record Building Parameter List
     DSECT      : SRBBK
     FUNCTION   : Overlays the parameter interface list
                  used between the dump modules and the
                  symptom record building modules.

                  HCPABF
     RELOCATION CONSIDERATIONS : None
     NOTES      : All modules get dynamic storage for this block except
                  HCPDMP.  HCPDMP will use part of HCPWRK for this
                  block.  Any CHANGES to this control block block
                  requires a recompile of HCPWRK.
