An IMS PCB, or program communication block, is defined by the user during PSB generation and describes an application program's interface to, and view of, an IMS database.

The IMS PCB details page shows the details for a particular IMS PCB. You access the details page by clicking an IMS PCB name on any page on which PCBs appear, such as the PSB details page.
