PURPOSE:To simplify the processing by separating and holding the decimal data part and the code part of a pack-form data held in a data holding means. CONSTITUTION:A separating means 121 separates the decimal data part and the code part of pack-form data held in a data holding means 111, and the decimal data part is held in a decimal data holding means 131 with the least significant bit matched to the word boundary or the half-word boundary. The code part is held in a code holding means 141 while including upper bits of one byte. since the decimal data part and the code part of pack-form data are separated and held, only the decimal data part can be processed without paying an especial attention to the code part, and the separated decimal data part is matched to the word or half-word boundary to perform the processing with a word or a half word as the unit, and thus, the processing is simplified. |
