PURPOSE:To make a processing to generate entry information in an object program unnecessary and to simplify the processing of a compiler, by holding the entry information of all of the execution time routines having possibility to be called from the object program in an entry vector. CONSTITUTION:The same number of execution time routines 17 as that of the execution time routines required in the object program 18 generated from a source program 20 by the compiler 19 are prepared, and they are discriminated by sequential numbers (1-n) starting from 1, and are constituted of execution time routine instruction parts 10 and execution time routine data parts 13. Also, at the front of the entry vector 1, a D register saving area 2 is arranged, and next, the arrangement of the address 3 of the execution time routine instruction part and the address 4 of the execution time routine data part are arranged in sequence of consecutive number for the execution time routine. In such a way, it is possible to simplify the processing of the compiler, and to use a memory required for the processing of the compiler effectively.
