UIPACK and YHIST

Care should be taken when using both UIPACK and YHIST, the CDF Histogram Package. UIPACK must be initialised before YHIST. Thus the correct initialisation sequence is:-

      STATUS = UIINIT(...)
      STATUS = HINIT (...)
      STATUS = HDINIT(...)

where HDINIT need only be called if the display portion of YHIST is to be used.
