Exceptional Control Flow - Computer Systems: A Programmer`s
... The simplest kind of control flow is a “smooth” sequence where each Ik and Ik+1 are adjacent in memory. Typically, abrupt changes to this smooth flow, where Ik+1 is not adjacent to Ik , are caused by familiar program instructions such as jumps, calls, and returns. Such instructions are necessary mec ...

OS 2200
OS 2200 is the operating system for the Unisys ClearPath Dorado family of mainframe systems. The operating system kernel of OS 2200 is a lineal descendant of Exec 8 for the UNIVAC 1108. Documentation and other information on current and past Unisys systems can be found on the Unisys public support website.See Unisys 2200 Series system architecture for a description of the machine architecture and its relationship to the OS 2200 operating system.
