Dear Jerome, Sorry, I'm not running your configuration. I cannot reproduce this problem with Sybase Adaptive Server IQ 12.6 and R 2.3.1 + RODBC 1.1.7 on WinXP SP2 or Linux 2.4.21-32.0.1.ELsmp #1 SMP Tue May 17 17:52:23 EDT 2005 i686 i686 i386 GNU/Linux.

The unexpected behaviour is that the last character of the string is truncated. As far as I can see, this happens when some strings are of length 501 or more.
