DOTV
Type: Adverb   (Logical,  > 0  =>  true)
Use:  If true, use of the TV is requested.  Additional meaning is
      attached to values > 1 by some tasks.  For example. XGAUS and
      friends use the TV for menus when DOTV is 2 and the terminal when
      DOTV is 1.  IMAGR chooses the initial facet to display by DOTV.
