What about ACB/RPL?

After OS/360, IBM introduced the Access Control Block (ACB) for all new access methods, while retaining the DCB for the old access method. Should this article mention the ACB and the related Request Parameter List (RPL)? Should there be a separate article? -- Shmuel (Seymour J.)
