CHDIR
Use
The CHDIR command may be invoked from a job, a session, a program, or in Break.
Pressing
Break has no effect on this command. You must have traverse directory entries
(TD) permission to each directory component in dir_name (refer to the ALTSEC command in
this chapter for more information on directory permissions.) The CWD is not changed if
