An optimization technique for optimizing binary codes in a language having access to a zoned decimal type variable and applicable to binary codes including instructions which can cause side effects. The optimization technique includes: detecting, for each variable, an area including access to a zoned decimal type variable and not including an instruction that can cause a side effect, from the binary codes read into a memory; and performing, in the detected area, a process for converting a zoned decimal type variable to a binary type variable, a process for deleting such a pack/unpack code that a converted result does not change even in case the pack/unpack code is deleted, from the binary codes, or a process for performing combination of the processes. |
