:>Subject: What happens to ALETs when an address space goes away?

:>Address space X task Y adds an ALET for A/S A to its DUAL (or the PASN).(Yes, 
in general a bad practice).

:>Address space A goes down.

:>Does the system EOM take care of invalidating ALETs that refer to it?  

:>Or does zOS wait for a reference which will fail the ASTESN match and then 
the ALEN-invalid bit is set? Or it just keeps failing on ASTESN/

:>Finally, when an  ALESERV DELETE is issued, is the ALET number available for 
reuse by zOS with a new ALESN? Or is it lost?
