Chief of operations Miles O'Brien found this program while checking several systems and tried to get access to this program. The computer denied him access to the program based on a personal security access code forged under O'Brien's name.
The program was protected by a series of encryption sequences, which Lt. Jadzia Dax attempted to decrypt with an adaptive program. According to O'Brien, they were lucky because they were working with a Cardassian computer, which limited the program to no more than seven encryption sequences.
After O'Brien and Dax decrypted the access code, 4-1-0-0-R-L-X, they discovered that the command protocols of this program included a system of sequential overrides for the security fields around runabout pad A – an escape route. (DS9: "In the Hands of the Prophets")
