* harbour/include/hbset.h
  * harbour/source/rtl/set.c
    * changed recently added hb_set*() functions to hb_setGet*()
      Please do not use these functions yet - it's possible that
      they will be removed soon.
    + added hb_setGetL(), hb_setGetCPtr(), hb_setGetNI(), hb_setGetNL()

  * harbour/contrib/libct/dattime2.c
  * harbour/contrib/samples/date.c
    * use hb_setGetCentury() instead of hb_setGetL( hb_set_century )
      we do not have hb_set_century SET switch so hb_setGetL() cannot
      be used

         CLEAR ORDER <order>

         SET ORDER TO TAG <(tag)> [OF <(bag)>]
         SET TAG TO [<tag> [OF <(bag)>]]
         REINDEX OPTION <eval> [STEP <step>]
         DELETE TAG <(tag1)> [OF <(bag1)>] [, <(tagN)> [OF <(bagN)>]]
         DELETE TAG ALL [OF <(bag)>]
         CLEAR SCOPE
         SET SCOPETOP TO [<value>]
         SET SCOPEBOTTOM TO [<value>]
         SET SCOPE TO [<value>]
         SET TURBOREAD ON|OFF
         MEMOPACK [BLOCK <size>] [OPTION <opt> [STEP <step>]]
         SET MEMOBLOCK TO <value>
         SUBINDEX ON <key> TO <(file)> ;
               [OPTION <eval> [STEP <every>]] [FILTERON] [EMPTY]
         SUBINDEX ON <key> TAG <(tag)> [OF <(bag)>] [TO <(bag)>] ;
               [OPTION <eval> [STEP <every>]] [FILTERON] [EMPTY]
         INDEX ON <key> [TAG <(tag)>] TO <(bag)> ;
               [OPTION <eval> [STEP <every>]] [FILTERON] [EMPTY] [SUBINDEX]
         INDEX ON <key> TAG <(tag)> [OF <(bag)>] [TO <(bag)>] ;
               [OPTION <eval> [STEP <every>]] [FILTERON] [EMPTY] [SUBINDEX]

      Unlike Ads*() functions the Sx_*() ones can be used with any RDD
      and will work if RDD supports necessary functionality.

      The global settings in SIx3 are RDD dependent in Harbour, f.e.
      in SIx3 Sx_MemoExt() change MEMO file extensions in all SIX* RDDs
      but in Harbour only in default RDD driver.
      In Harbour default trigger function "Sx_DefTrigger" is not
      enabled by default. If user needs such functionality then he
      has to enable it himself using
         rddInfo( RDDI_TRIGGER, "SX_DEFTRIGGER", [<cRDD>] )
      f.e. this code:
         init procedure sx_inittrig()
            local aRDDs := { "DBF", "DBFNTX", "DBFCDX", "SIXCDX", ;
                             "RMDBFNTX", "RMDBFCDX" }
            local aRDDList := RddList(), cRdd

            for each cRdd in aRDDs
               if ascan( aRDDList, { |x| x == cRdd } ) != 0
                  rddInfo( RDDI_TRIGGER, "SX_DEFTRIGGER", cRDD )
               endif
            next
         return
      sets SX_DEFTRIGGER as default trigger in DBF* based RDDs.

      I still do not allow to encrypt tables with memo fields to not
      replicate SIx3 bugs which may cause data corruption.
