I'm not sure where it is documented (if at all) but the URGENT
parameter gives the Sybase DB-Library the ability to pass "out of
band" data (dbcancel) to the server. The main reason you would want
to enable this feature is to be able to abort a query once it's been
sent.
We found (quite a while ago) that with using Microsoft Access going
through Microsoft ODBC to Sybase DB-Lib (ver??) to a Sybase server, we
could not abort a query using <CTRL><BREAK>. Now I believe the
specifics were in that in the Native implementations of IPX/SPX out of
band data wasn't supported. By adding the 'URGENT' parameter to the
end of the entry in Win.ini as you've done above solved the problem.
I don't know of any side-effects to always having that option
"enabled."
This is no longer a problem if your app uses CT-Lib.
