Hereafter, is all the information I have on it.

	SET WATCH is an unsupported, undocumented feature of VMS (4.x, 5.x)
	It needs CMKRNL. (CMEXEC may suffice)
        
	As such, it should be used with caution. 

It executes the image SYS$SYSTEM:SETWATCH.EXE who simply sets a few bits in 
the high byte of PIO$GW_DFPROT in your P1 space.  

It gives information on all the accessed files in a batch or interactive
session, the information to be displayed is selected with the class parameter
(see below).
 It is a very handy tool to get information on files used by an executable 
for which no documentation is available.

It is activated via the DCL command  SET WATCH FILE/CLASS=xxxx
	xxxx may take the following values:
		ALL			(gives all the information)
		ATTRIBUTES              (gives the attributes of each
					open files)
		CONTROL_FUNCTIONS	(*)
		DIRECTORY_OPERATIONS    (*)
		DUMP           		(Gives the FIB contents for each
					referenced files)
		MAJOR_FUNCTION          (*) (Access, deaccess, lookup)
		QUOTA_OPERATIONS        (displayed QUOTA changes)
		NONE			(To deactivate SET WATCH)

(*) signals the more interesting classes.

All is very verbose, Major is usually sufficient.  This command mimics
the SET WATCH FILES command from the Tops-10 operating system.  The one
thing it's missing is telling you the directory an accessed file is in.
The reason for this is that by the time the XQP (which is what's reporting
all of this info, by the way) gets around to telling you about something
it's really operating by file ID.
