[Rd] RODBC

[Prof Brian D Ripley]

Several of you have kindly sent me examples of bugs in RODBC, but none
of them reproduce on my systems.  I am fairly sure I know what is
happening, and that it is client-specific.  (Do empty strings get returned 
as "", NULL or skipped?)   Also, empty character fields were getting mapped
to NA.  There's a comment in the code that fields need to set to a null
string, and that was only being done for the first row.

If my diagnosis is right, I have a fix (and have simpilfied the code a
lot en route).

http://www.stats.ox.ac.uk/pub/bdr/RODBC/RODBC.zip  (Windows)

I'd be grateful for confirmation (or otherwise).

BTW, although I have altered the code to compile under R-devel, it does not
work correctly for me as yet.
