1 DEF

	DEF is a foriegn command which allows one to change ones default
 directory in a simpler fashion than using the SET DEFAULT command.  
 At the same time, if one has allowed privileges, and if SETUIC is on the
 system and defined as a foreign commmand, one's current UIC is changed to
 the UIC of the target device/directory.   To change ones directory type

		DEF  directory_name

 Typing just  DEF .sub_directory   will switch you to 

		[directory_name.sub_directory].

 Typing just DEF [-]  will back you up one level toward the root directory.
 
 	DEF takes a more general syntax in that it also will accept
 both devices and directories. ie

		DEF  DEV:DIRECTORY

 If the device is specified, the ':' must seperate it from the directory
 with no intervening spaces.  The [ and ] are optional.
 
   DEF has two special symbols "." and "$".  DEF $ will move you back to
 your login directory while DEF . will move you to the last directory you
 were on. DEF maintains a symbol LAST_DEFAULT for each user which contains
 the last directory for which DEF was used to move to.

 If you try to specify a directory or device which does not exist, DEF will
 issue a warning message and not execute the command.
