===How to move to a different directory===
Use the SET DEFAULT command. You can use an absolute directory path or a relative directory path.
<pre>
$ SET DEFAULT disk:[dir.subdir]	      !Moves to specified path.
$ SET DEFAULT [.subdir]		      !Moves one level into subdirectory subdir.
</pre>

Use the CD (i.e., change directory) command (this calls the script $ @SCOM:CD.COM).
<pre>
$ CD subdir	                      !Moves into subdirectory subdir.
$ CD subdir1 subdir2	              !Moves into subdirectory subdir1, then into subdir2.
$ CD ..		                      !Moves up one level (i.e., out of one directory).
</pre>

What if you don't know the directory on the disk? For example, how can you change to DISK5 if you 
don't know what user is on that disk? You can enter the following:
<pre>
$ dir disk5:[000000].dir
</pre>
But you will need to be logged in as <code>system-user</code> in order to use that command.

$ DIR/SINCE=TODAY		      !Lists all files created today.
$ DIR [...*.aim]                      !The "..." indicates to do so recursively (i.e., counting all files in all subdirectories).
$ DIR/SIZE	                      !Lists each file and its size.
$ dir/size/grand_total [.subdir...]   !List the total size of all files in the SUBDIR directory.

Or if you are creating a directory on a new disk (log in as user <code>system</code>):
<pre>
$ create/dir/log/vol=1 disk7:[xtremect2.abc] /own=xtremect2
</pre>

If the owner of the new directory is not specified (qualifier '/own=<owner>), it will be assigned to the user as which the command has been entered.
