+Run :info and look at the introductory information about the
+filesystem. I did not find that it covers directory operations very
+well so here is what I have found out. ITS does have a process tree
+(try the PEEK command) but does not have a directory tree. There is a
+Master File Directory MFD (try DSKUSE * or DIRED and then MFD. Use
+"Q" to quit after either of those.) and User File Directories UFDs one
+level deep only. The only way to remove a directory is to delete its
+contents and run the salvager. The salvager is the ITS equivalent of
+fsck and will automatically be run at boot time. To create a new
+directory provide certain options to the open UUO (ITS equivalent of
+system call; try the DOC UUO command.) Since the PRINT command calls
+the open UUO you can create a directory using print:
+
+:print ..new. (udir) dirnam;
+
+Where dirnam; is the name of the directory to be created. Directory
+names are limited to six characters.
+
+Missing from this ITS distribution is the INQUIR database. It
+contains user information. There were too many personal details in it
+and no one has been able to scrub it so it was left out. This means
+you cannot have a complete user account yet. The best you can do is
+to pick a user name and make yourself a directory with that name and
+put a login script in it. In this example the user "user" is created:
+
+:login user
+:print ..new. (udir) user;
+:emacs login user
+[add startup code like ":tctyp vt52" and ^X^S to save ^X^C to exit]
+
+You log out with <ALTMODE><ALTMODE>u which is [Esc][Esc]u and
+represented in the documentation as $$u
+
+The ITS equivalent of $PATH is implemented by scanning all
+directories for files for files with TS as the first name and
+the second name set to the command you issued. By convention
+most commands are in the SYS; SYS1; ... SYSN; directories.
+ITS supports symlinks via the LINK command and TS name is often
+a symlink.
+
+ITS equivalent of job control works by typing ^Z to interrupt the
+current program. To get back to the DDT prompt "*" use $^K
+
+Don't like DDT as the shell? Try MONMOD to use monitor mode where
+the colon is printed for you. DDTMOD get you back. Or try SHELL
+to bring up a UNIX-like shell.
+
+Zork was developed in MDL (muddle) on an ITS system but apparently it
+suffered from being too popular. Try the ZORK command to see what
+happened. A scrap of MDL source code is left (:find @muddle) but I
+don't know how to MIDAS it.
