Yes, it does, for text processing...

What exactly would dbsqlsend, as implemented above, do? According to
the DB-Lib manual, it "Send[s] a command batch to the server and do[es]
not wait for a response. "
How would using your implementation differ from the standard C
implementation? What's involved in getting Asynch I/O to work? If
dbsqlsend doesn't wait for a response, isn't that pretty much what I'm
looking for (since dbsqlok is already implemented)? Or is there more
involved that I'm missing?
I might add this sometime in teh future, but time is short...
Actually, time is infinite (or so they tell me). *Life*, on the other
hand... :-)
