A compiler program creates a program, which is executed on a platform where use of a pointer is limited and that can perform a pointer operation without specifying addresses allocated to a memory. When a source code, which is related with the pointer operation to be executed for data having references for simultaneously identifying respective data and offset information for simultaneously specifying positions in the data identified by the references, is read, a code for performing the pointer operation using a pseudo-pointer having a predetermined data length is created by the compiler program based on information simultaneously specified by the references for identifying the data and the offset information.
