The '''Convergent Technologies Operating System''' '''(CTOS)''', also known variously as '''CTOS''', '''BTOS''' and '''STARSYS''', was a modular, [[message-passing]], multiprocess-based [[operating system]].

==Overview==

''''''CTOS'''' had many innovative features for its time. System access was controlled with a user password and Volume or disk passwords. If one knew the password, for example, for a volume, one could access any file or directory on that volume (hard disk). Each volume and directory were referenced with delimiters to identify them, and could be followed with a file name, depending on the operation, i.e. {Network Node}[VolumeName]<DirectoryName>FileName.

It was possible to custom-link the operating system to add or delete features.
