Thanks, Nick, I see I have to modify my theory to fit the facts.  Bill
linked my new bcp.c unit test to Sybase's libraries, and got no message.
His experience matches mine: I've never seen that or coded against it.  

It would make sense that bcp_batch() would not emit that message, because
the application *knows* the batch was just committed based on the return
code from bcp_batch().  

It would also make sense for bcp_exec() to emit that message if BCP_SETL had
been called to set a batch size for the loading of an external file.
There's no other way the application could be notified of the ongoing status
of the load.  

I would be willing to believe that informational messages can be returned
INT_CANCEL without harm.
