Figure 70 illustrates some of the control blocks used to support remote DL/I.
The DL/I interface parameter list (DLP) is described in DL/I interface parameter list (DLP).
The remote PSB directory (PDIR) contains an entry for each remote PSB that can be used from an application program.
The remote scheduling block (RSB) is acquired when a CICS® task issues a PSB schedule request for a remote PSB. The RSB is freed when the task issues a SYNCPOINT or a DLI TERM request.
See CICS Data Areas for a detailed description of these control blocks.
