James, thanks for the datum.

Hmm... not saying that I am equal to the task, but if I were to try to
"enhance" TDS/Ethereal, there are a couple of basic TDS 5.0 questions I have:
One of the things that has bugged me about Ethereal's interpretation of TDS 5
is that it sort of stumbles when it encounters a TDS_KEY (client side) or
TDS_ROW (server side). To resolve this, I assume I would have to hunt
backwards through the stream, for the related ROWFMT(2) and/or PARAMFMT(2).
Sybase's description of the cursor tokens makes this challenging: apparently
you pass the PARAMFMT after the CURDECLARE, and the PARAMS in the CUROPEN, to
which the server responds with a ROWFMT accompanying the CURINFO (describing
the subsequent ROWs and KEYs). All of these associations appear to be
inferred, as there are no identifiers relating one to the other.
Can I assume that only one ROWFMT is "active" at a time?
Can I assume that if the PARAMFMT does not immediately precede a PARAMS, I
should use the PARAMFMT supplied with the most recent CURDECLARE?

Thanks for any information.

(still no news on "SQL Anywhere CMDSEQ"?)

Quite on topic, it seems to me.

Brian Bruns did the original and afaik only work to teach TDS to Ethereal.
I wouldn't expect him to contribute further to it. Someone else will
have to pick up the ball.
