Command XJL was an automatic transporter program code devised by Seska. The command triggered an automatic site-to-site transport that she used to beam herself to another location. This program was similar to one used by Wesley Crusher. (TNG: "The Game" ) In 2371, after being exposed as a traitor by Commander Chakotay and Lieutenant Tuvok, Seska managed to escape from the USS Voyager to Maje Culluh's Kazon vessel by using command XJL to beam her off the ship.
