ENDBR request processing

The ENDBR request is used to end a browse session on a file. To avoid deadlocks, ENDBR must be issued when the browse session is complete.

VSAM processing

  1. An ENDREQ request is sent to VSAM. This frees any VSAM strings that are held, and relinquishes shared control of the CI.
  2. The VSWA for the operation is released.

BDAM processing

The FIOA that was used for the browse session is released by using a FREEMAIN request.
