Intermediate code execution system, intermediate code execution method, and computer program product for executing intermediate code

摘要

An intermediate code execution system (10) which has processing modules (11, 12) which execute each of processing commands included in a predetermined command system and sequentially interprets and executes intermediate codes written in accordance with the command system comprises a command acquisition portion (13) which takes out a processing command from the intermediate code, a first processing command execution portion (15) which makes judgment upon whether that processing command corresponds to each of selected processing commands selected from processing commands included in the command system, and selects and executes the processing module (11) corresponding to the selected processing command if the taken-out processing command corresponds to that selected processing command, and a second processing command execution portion (17) which specifies a type of a processing command which has not been executed in the first processing command execution portion (15), and selects and executes the processing module (12) corresponding to that processing command.
