Thanks for the enlightenment.  Now I know where to look, and found the 
following from 1.2 show application agi:

"Returns -1 on hangup (except for DeadAGI) or if application requested 
hangup, or 0 on non-hangup exit."

Apparently this AGISTATUS is a 1.4 thing, and probably still very 
simplistic.  Just wonder why all AGI commands carry sophisticated return 
codes.
