Abstract

PURPOSE: To make it possible to trace interruption timing information when an interruption is caused, by stacking the contents of a location counter stored with program status word address PSW in a memory region.
CONSTITUTION: If an interruption is made during the execution of a program, controller 102 makes a check on the state of extenrnal indication switch 105 indicating a tracing function and when the tracing function is effective, PSW displaying the state of program 4, location LOC cna interruption-kind code information 106 are stored in queue 104 of the main memory assigned by point 103. With the tracing function effective, the state of an interrupted program, namely, information 106 is stored queue 104 sequentially at every acception of an interruption and when the queue becomes full, order one is irased and up-to-date information is stored. The detection of a abnormal program and the mutual state between the program and hardware can both be grasped by checking the contents of the queue.
