PURPOSE:To attain the call of procedure between the program executing means of different storage protecting systems, by providing a call/return means between procedures of different storage protecting systems and a means which converts the storage protecting information of a parameter address. CONSTITUTION:The callers 101 and callie 102 apply a key protection system and a ring protecting system respectively. Thus a reception converting means 107 obtains the storage protecting information, i.e., the key of the caller 101 out of a protecting information saving area 106 and sets the output of a protecting system deciding means 109 converted by a table to the ring of the address information. A delivery converting means 110 clears the ring to zero to convert the address information of a ring protecting system into that of a key protecting system. |
