SOFTWARE RESOURCE TRANSITION SYSTEM AND TRANSITION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To achieve downsizing without changing a host program.;SOLUTION: A compiler 290 for downsizing includes a runtime table wherein a plurality of runtimes corresponding to OSs or input/output statements of host program sources are stored. When it is determined that an OS or the like stored in the runtime table is included in an input host program source, the runtime is designated as a parameter of the compiler to read in a program source for a host, and the program source is decomposed into tokens to generate an object code. When it is determined that a runtime call is necessary for an instruction statement of the object code and that the parameter is designated for compilation, the object code is generated so as to call the runtime stored in the runtime table, and the generated object code is inserted to a compiled server execution object to achieve downsizing.;COPYRIGHT: (C)2010,JPO&INPIT
