PURPOSE: To resolve the burden of recompilation of all related object programs by generating an object program which can take over and hand over the control table from and to another object program having a different control table form.
CONSTITUTION: When the object program having procedures to hand over the control table to another object program or take over the control table from another object program is generated, a processing 7 to convert the control table into a control table in a new form to be used in this object program is built in the stage of semantic analysis if the control table of the another object program to be taken over is in the old form. If the control table of another object program to be handed over is in the old form, a processing 8 to convert the control table in the new form used in the object program into the old form is built in. Consequently, the control table is correctly referred because of conversion to the control table form of the object program though the control table is taken over and handed over between object programs different in control table form.
