Abstract :
The new application program which is used to control the closed orbit in the Tevatron is described. Unique features include the ability to acquire closed orbits at all energies on one ramp and provide dipole settings which smooth the orbit and are continuous as a function of energy. The program is also used to correct for the orbit distortions caused by the placement errors of the low beta quadrupoles as the transition is made from the injection optics to the low beta optics.<>
