PURPOSE:To recognize a program execution locus in a flowchart style and a source program image by collecting jump source address information and jump destination address information in a range specified whenever a jump instruction is issued and storing them in a bulk memory device. CONSTITUTION:The titled system is provided with the 1st controller 100 to transmit the jump source address information and the jump destination address information at the time of executing the jump instruction, the 2nd controller 200 to receive the transmitted address information, the bulk memory device 500 to accumulate the received address information, a bulk memory device control part 400 to control the bulk memory device 500, a memory device 300 to store source program image address corresponding information, a printing and output device 600 and a screen display device 700 within the specified program. Without trace information output instruction from a compiler, a trace range is specified at the time of executing a program, whereby the program execution locus is collected and displayed in a flowchart style and a source program image.
