PURPOSE:To reduce the size of a program by displaying the existence of the attribute of input data and whether the attribute is allowed or not in accordance with the flag of a bit pattern and detecting an error in the input data by a unified method independently of the sort of input data. CONSTITUTION:A data processor for a program developing tool is constituted of a CPU 1, a main storage device 2, a storage control device 3, an external device 4, a display device 5 to be a man-machine interface, and an I/O control device 6 and error retrieving information 11 prepared in each field to be the receiving unit of input data is stored in the device 4. Since the existence of the attribute of input data and whether the attribute is allowed or not are displayed in accordance with the flag of the bit pattern, an error in the input data can be executed by the unified method independently of the sort of the input data. Consequently, the size of the program can be reduced. |
