<P>PROBLEM TO BE SOLVED: To solve the problem in which an optimization technique for directly executing optimization to a binary code of a language having access to a variable of a zone decimal form, and applicable to a binary code having an instruction which can be an adverse effect is demanded. <P>SOLUTION: The present invention provides an optimization technique for optimizing a binary code. The optimization technique includes steps of: detecting an area without an instruction which includes access to a variable of a zone decimal form and can be an adverse effect for the respective variables from the inside of the binary code read in a memory; and performing, in the detected area, processing for converting the variable of the zone decimal form into a binary type, processing for deleting from the binary code a code of PACK/UNPACK of which the converted result does not change even when the code of PACK/UNPACK is deleted, or processing in combination of them. <P>COPYRIGHT: (C)2013,JPO&INPIT |
