PURPOSE:To eliminate unnecessary stand-by operation and restoring operation, and to speed up processing by calculating and storing the logical product of all identifiers in an overlay area during load processing, and inhibiting stand- by operation to the overlay area when a specific logical result is obtained. CONSTITUTION:Each program module consists of control information and a program body, and the control information contains a program body, and the control information contains a program iD, program length, a program format, an arrangement address, a generation date, etc. Then, the program format is provided with flags for specifying a registered, a rearranged, a vector-added, or a re-entrant program. The flag (f) of a re-entrant state is set to ''1'' for re-entrant structure, or to ''0'' for other structure. Then, all programs loaded into an overlay area are provided with flags F and when the flag is ''1'', the all program modules in the overlay area are re-entrant, and stand-by operation to the overlay area is not performed. |
