The exits must follow standard linkage conventions. They must save the registers on entry and restore the registers when they return. The exits must be reentrant, refreshable, and reusable. The exits are not APF-authorized. The exits can use any of the TSO/E service routines. For a description of the service routines, see . In some cases, you may not need to write a termination exit. This
depends on:
If the initialization exit obtains a system resource, you must write a termination exit to free the resource. For example, if the initialization exit obtains storage to return a new command buffer to the TEST command processor, you must provide a termination exit to free the storage. The initialization exit can change TEST operands using the command
buffer. The exit checks the command buffer it receives and determines
whether to change any operands. To change the operands, the exit
