PURPOSE:To prevent destruction of a memory by providing a memory key information designating means additionally to a resultant information storage memory address designating means as an operand of macro instructions. CONSTITUTION:A macro instruction user designates a resultant information storage memory address which is the input of a resultant information storage memory address designating means 11 and key information which is the input of a key information designating means 12. The same key information as contents of a resultant information storage memory is designated. A key information comparing means 13 compares the contents of the resultant information storage memory designated by the resultant information storage memory address designating means 11 with key information designated by the key information designating means 12, and resultant information is stored in the memory address designated by the resultant information storage memory address designating means 11 if they coincide with each other. If they do not coincide, an error reporting means 14 is started to report error to the user. In this case, resultant information is not stored in the resultant information storage memory. |
