PURPOSE:To facilitate an easy production of program without consciousness of the address containing a data block to access is stored, by installing a table to store a flag to indicate the interpretation and the segment number of the contents to be stored by each data block. CONSTITUTION:A flag to indicate the interpretation and the segment number stored in a data block are stored in a table 12, and the instruction under execution in stored in a display register 14 for the segment that is executing an instruction. At the same time, a setting instruction 1, a reading instruction 2, a writing instruction 3 and a resetting instruction 4 of an FF7 are supplied to a decoder 5 to be decoded. Then the segment number is read out of the table 12 for the data block that refers to the instruction and compared with the segment number that is being executed by the register 14 through a comparator 16. When a coincidence is obtained, the flag is not set. The flag is set when no coincidence is obtained. Furthermore the segment number stored in the block is set to a segment disignating register 13. Thus the formation of program is facilitated. |
