Subprocess

A subprocess is a type of process in OpenVMS that depends on its parent process for resources and lives for the life of its parent process. Subprocesses can be generated with the SPAWN or PIPE command. The ATTACH command can be used to attach to a subprocess (or a different process) and LOGOUT to kill the subprocess, returning to the parent process. In the output of SHOW SYSTEM, subprocesses are marked with the letter S.
