Something we have done as the grunts (because we WANT to know if a product of 
value is soon to expire) is to set up automation (ops/mvs for example) to look 
for and email such soon-to-expire occurrences to we grunts - who then scream to 
our managers to scream to our contracts team to get the license paid

Subject: Re: [IBM-MAIN] WTO for message that will require explicit deletion?

@Peter, thanks.

Frankly, the documentation of the more esoteric aspects of WTO seems haphazard 
to this observer. I think WTO's clarity of documentation suffers from the 
various things that have been layered on over the years such as MCS. As I wrote 
in the OP, the idea that DESC=3 requires an explicit delete comes from this in 
the doc: "If the task can determine when the operator has performed the action, 
the task should issue a DOM macro to delete the message." That is not logically 
the same as the statement "the message will hang out until it is explicitly 
deleted" but for better or worse that is what I inferred.

An automatic DOM at step termination will preclude this approach for me, but 
does make logical sense and as you say is consistent with how MVS tends to do 
things. I intend to run an experiment with -- purely as an experimental hack -- 
a one minute or so delay before the jobstep task ends -- just for my own 
curiosity.

OTOH, there is this: "When using the LINKAGE=BRANCH parameter, the system does 
not automatically delete a WTO issued by a caller in SRB mode. A caller in SRB 
mode must issue the DOM macro to explicitly delete any action message when the 
calling program ends."

That would appear to be an approach that would cause a message to "hang out"
past end of jobstep. Not sayin' it's a good idea, just sayin'.

Charles,

You started with
<snip>
I have an APF-authorized batch program that I want to have WTO a message that 
will hang out at the bottom of the console screen until it is explicitly 
deleted </snip>

I'm quite sure that the system will automatically DOM a message upon 
termination of the jobstep of the issuer. 
That should not be much of a surprise. I'd hope it is mentioned somewhere (for 
completeness, not suggesting that it's at all obvious). That might be thought 
not to violate your requirement unless you added "and not cleaned up at step 
termination". Not all that many things fall into the category of "not cleaned 
up at step termination".  Obtaining of common storage, of course, is one.
