Yeah that's probably cleaner.

I think you only need:

  H_CPPR
  H_EOI
  H_FUNCTION
  H_GET_TERM_CHAR
  H_HARDWARE
  H_IPI
  H_LOGICAL_CACHE_LOAD
  H_LOGICAL_CACHE_STORE
  H_LOGICAL_CI_LOAD
  H_LOGICAL_CI_STORE
  H_LOGICAL_DCBF
  H_LOGICAL_ICBI
  H_PARAMETER
  H_PUT_TERM_CHAR
  H_SET_DABR
  H_SUCCESS
  H_XIRR
  KVMPPC_H_RTAS
