DEVICE FOR CONTROLLING MESSAGE OUTPUT OF PROGRAM SIMULATOR

PURPOSE:To reduce the number of times of output of message data by displaying the message data stored by prescribed position achievement by collecting after the simulation of a tested program is started. CONSTITUTION:The message data outputted from a message output control means 6e is stored to a message buffer means 6f in each simulation execution of the tested program. After the simulation of the tested program is started, the message data stored to the means 6f by the prescribed position achievement is outputted to a screen control means 6g and displayed to a display device 2. The display request signal of the message data is inputted from the input terminal of the device 2 and the message data to correspond to the display request signal is selected from the means 6f by a screen display data selecting means. Then, the selected message data is outputted to the means 6g by a scroll screen output means and displayed to the device 2.
