I just stumbled upon this field in SYS1.MODGEN, member IHAECVT. This appears at first glance to be for the TRAP, TRAP4, and perhaps the <do something> AND TRAP instructions. But I don't really see _anything_ else in SYS1.MACLIB or SYS1.MODGEN that references this field.
Anybody got a link to the secret documentation? Or is it one of those ".... but then I'd be forced to kill you" type situations. -- I have a theory that it's impossible to prove anything, but I can't prove it.
