| - This song is used by Harvestasha VISTA to shift into battle mode, but it actually is a little more complex than that: the song title comes from a file manipulation command used in the UNIX operative systems, which changes the access privileges to a determinate file. Firstly, the song title is read as "Change Mode Seven Zero Zero N" and it has the following meanings: the "b" preceding the numbers specifies they are in binary format, and the numbers are grouped in threes to indicate different groups of people, with the first three digits corresponding to Harvestasha, the next three correspond to people in the same group as her (in other words, Tyria and Ayatane), and the final three to everyone else. Now well, each group of three have the following meaning: the first number is reading access, the second writing access, and the third is execution access, with "0" meaning the permission to accomplish one of these tasks is removed and with "1" meaning that particular permission has been granted. Finally, the "/n" at the end is an order to execute the command preceding it. To summarize this, it means that Harvestasha is giving herself all the possible privileges on the Tower's systems and removing them from everyone else, including Tyria, leaving them powerless to do anything. Due to this, this mode change is only reserved for extreme emergencies, such as the Tower's Mainframe being directly attacked by a virus or something else. There are other 512 possible mode changes, but since several of them could cause Harvestasha's AI engine to go haywire due to an erroneous configuration, most of them are configured as Impossible Patterns so no one can ever use them. Similarly, chmod's was originally created after Harvestasha's completion to bestow access rights to the humans in case something happened to her and that created a security hole in the Tower's systems, but due to Clustania's birth and the Necrofamilies' dark schemes, the humans could never use this program in a way that benefited them. This song plays during the battles against Harvestasha's battle mode, and strangely enough, it also plays in the battle against Ayatane, despite not having an actual relationship to him.
