B. Environment Variables : TERM_INGRES
Share this page                  
TERM_INGRES contains the terminal designation for the terminal upon which you are executing one of the Vector forms-based products, such as QBF or VIFRED. It is usually defined locally by the individual user.
TERM_INGRES is most conveniently set in a .login or .profile file. TERM_INGRES takes precedence over TERM in defining the terminal type. It allows TERM to be defined differently for use by other Linux programs such as vi.
