Exit
Terminates the calling process

OS9 F$Exit 103F 06

Entry Conditions

B status code to return to the parent process

Exit Conditions

The process is terminated.

Additional Information

The Exit system call is the only way a process can terminate itself. Exit deallocates the process’s data memory area and unlinks the process’s primary module. It also closes all open paths automatically.
The Wait system call always returns to the parent the status code passed by the child in its Exit call. Therefore, if the parent executes a Wait and receives the status code, it knows the child has died.
Exit unlinks only the primary module. Unlink any module that is loaded or linked to by the process before calling Exit.
