PURPOSE:To improve the execution efficiency of an objective program by checking whether all the values of respective elements constituting a record constant are static or not and determining an instruction to be formed based on the static information. CONSTITUTION:When a record constant is supplied from a source input means 1, a static state deciding means 2 decides whether all the values of the elements constituting the record constant are static or not. An instruction determining part 3 previously assigns the record constant in a memory based on the static information obtained by the means 2 and the sort of characters appearing the record constant and determines whether program formation can be attained only one substitutive instruction or only one comparing instruction or not. The instruction formed by the means 3 is outputted by an instruction output means 4. Thus, the execution efficiency of the objective program can be improved.
