Summary
The control point, or dispatcher, is the location through which control files effect program execution. This gives the user a single context for controlling his system. Without this single ontext, the user is constrained by the system to interact in predetermined ways. Control points provide a foundation for default error handling. Backtracking is possible because the control point's state is fixed. Control points are implemented by a repeat loop with control file access acting on a case statement. (cbb 5/80)
