PURPOSE:To make verification of a procedure program for processing information easy, by changing the flat of an executed procedure only out of flag areas provided in part of translated codes corresponding to each procedure. CONSTITUTION:An information processor 100 is equipped with a translating means 102 which translates a source program in which information processing procedures are described into codes 105 and an interpreting and executing means 103 which interprets and executes the translated codes 105. The translating means 102 translates a source statement 108 having a line number 107 into a string of codes composed of a pointer 109 containing the line number, instruction 110, operand 111, and executed/unexecuted flag 106 and stores the code string in a storage means 104. Upon actually executing the codes 105, the interpreting and executing means 103 sets their executed/unexecuted flags 106.
