I'm not clear what you want to Stata to _do_. However,
here's one possibility. 
Suppose your magic number is 2. 
After -dwstat- you could get Stata to 
display a message, e.g. 
if r(dw) <= 2 { 
	di as err "{hline}"
	di as err "Durbin-Watson is <= 2"
	di as err "{hline}"
} 
Is that what you want? 
Stata used to have a -beep- command, but I can't 
get Stata to -beep- at me any longer.
