HB_SETKEYSAVE()

Returns a copy of internal set-key list, optionally overwriting
---------------------------------------------------------------------------------

 Syntax

       HB_SETKEYSAVE( [ <OldKeys> ] )  

 Arguments

        <OldKeys>   is an optional set-key list from a previous call to 
                  HB_SetKeySave(), or NIL to clear current set-key list

 Returns

       Current  set-key list    

 Description

      HB_SetKeySave() is designed to act like the set() function which
      returns the current state of an environment setting, and optionally
      assigning a new value.  In this case, the "environment setting" is
      the  internal set-key list, and the optional new value is either a
      value  returned from a previous call to SetKeySave() - to restore
      that list,  or the value of NIL to clear the current list.

 Examples

     local aKeys := HB_SetKeySave( NIL )  // removes all current set=keys
     ... // some other processing
     HB_SetKeySave( aKeys )
