To create or delete a file directory on a User Disk Pack, or to
change the password or file protection values for such a directory,
first ASSIGN and mount the UDP, then type the monitor command
	UDPUFD PRJ,PRG
where PRJ,PRG is the name of the directory in question.  You must
know the pack password to create a new User File Directory on the
pack; to modify or delete an existing UFD, you must know its own
password (if any).  Before deleting a UFD you must first delete
all the files in it, e.g., by typing
	DELETE UDP1:*.*[PRJ,PRG]
The UDPUFD command runs a program in your core image.

For more information about the UDP, see the file UDP.BH[UP,DOC].
For more information about file protection, read LOGIN.BH[UP,DOC].
