Event handler routines

Each member in an enclave that provides a signature CSECT or appears in the dependent member list of a signature CSECT is also required to have an event handler routine. The load name of this routine must be CEEEVnnn, where nnn is the decimal member number. As an example, the event handler routine name for COBOL is CEEEV005. This routine must be available to the Language Environment load service. All calls of the event handlers use an OS-style parameter list. R1 points to an address list which points to the specific parameters. The event handlers are always called in AMODE 31. The interface to the event handler routines for member-specific initialization and termination is described in Member event codes for initialization and termination. For each of the event handlers, see Event handler calls.
