<para>
These are shell &quot;built in&quot; commands used to change OS-9's working
data directory or working execution directory. Many commands in OS-9
work with user data such as text files, programs, etc. These
commands assume that a file is located in the working data
directory. Other OS-9 commands will assume that a file is in the
working execution directory.

<para>
NOTE: These commands do not appear in the CMDS directory as they
are built-in to the SHELL.
