VIEW_SWAP()                                                         C_EXAM05
   Changes from the current viewport to another.

   Syntax
         nI  = VIEW_SWAP(nViewHandle,nHideView)

   Arguments
         nViewHandle Sets the current viewport.
         nHideView   Sets the hidden viewport to swap with. View number
                     (0-15).

   Returns
         nI          Returns a 0 if nViewHandle is not legal.

   Description
         VIEW_SWAP() changes from the current viewport to a viewport specified
         by the view handle. If the nHideView argument is non-zero, the
         viewport being left is hidden. Otherwise the viewport remains
         visible. If the new viewport being switched to was hidden by a
         previous call to VIEW_SWAP(), the new viewport is automatically made
         visible.
