- 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.
