NORD-50 monitor

The NORD-50 monitor is a subsystem in the SINTRAN operating system, supervising execution of NORD-50 programs.

To use the monitor, it must have been loaded into SINTRAN as an RT program. The monitor is then started under SINTRAN by typing @N-50 on a terminal connected to the system.

Main tasks of the monitor are:
 * loading programs from files into NORD-50 memory. These programs must have an executable format prepared by the NORD-50 loader. (:NOR5)
 * starting the programs.
 * reporting errors during program execution.
 * examining the NORD-50 registers / memory after the programs have come to a stop (normal or abnormal stop).
