This submission contains three corrections/updates to previous submissions
to the VAX tape.

1) ASK.MAR is a utility to "inquire" for an answer from a command procedure
and timeout if there is no reply within some time frame.  It is on the
Fall 82 VAX tape.  There is a comment that this is very useful for booting
the system (if no operator is present, optional features will default in).
However, you need to add the line
	$ASSIGN OPA0: SYS$COMMAND
to SYSTARTUP so the ASK knows where the answer is coming from...  Hopefully
this will lessen the number of calls from people getting invalid I/O messages.

 2) USS.MAR is an example of a user written system service submitted on the
Fall 83 VAX tape.  It is used to read the microsecond clock.  Unfortunately 
the version copied out to tape was not the version I was using; there is 
one small error.  The DIFFTIME routine should save all the registers it uses
in the entry mask.  There haven't been any questions about this one yet, but
my face is red anyway.

 3) SNOBOL was submitted on the Fall 82 VAX tape.  The source for the macros
on the tape was accidentally truncated, however, so people wishing to modify 
and reassemble had a problem.  The full source for the SNOBOL interpreter is 
included in this submission.

Librarian's note:  Note that items 1 and 2 are comments regarding the Fall 
1984 tape - ASK.MAR and USS.MAR are not repeated on this tape.
