PROBLEM TO BE SOLVED: To allow one program to use a class instance generated by another program and call a method in the latter program by reading the pointer to method information out of a method table and branching off to the method. SOLUTION: A method number determination part 208 of a static link part 207 sets a method number determined uniquely in a class to a method included in a source program. A method table generation part 209 generates a method table according to the method number. A method call instruction conversion part 210 converts the arguments of a method call instruction when the method call instruction is present in the source program. A method table read part 215 of a virtual machine part 214 when executing the instruction converted by the method call instruction conversion part 210 reads the contents of the method table out and a method dispatch part 216 calls the method in the found address.
