X-Mailer: Apple Mail (2.936)these are flags associated with K objects.Ignore them for the moment as they are not easy to use except for sorted or unique (s and u).felixOn 6 Oct 2009, at 20:05, dbtouch wrote:>> What does it mean?>> On Oct 5, 4:11 pm, Attila Vrabecz <attila.vrab…> wrote:>> http://kx.com/q/c/c/readme.txt&gt;&gt;&gt;&gt; u - supg flag>>>> Regards,>> Attila>> On 5 Oct 2009, at 21:06, dbtouch wrote:>>>>>>>>>>>>> Hi, KDB Developers>>>>> May I know what u member in K structure is used for?

X-Mailer: Apple Mail (2.936)yes, they are very thigh linked with structures inside kdb.you can flag sorted or unique attribute but you should do this only from q rather than c interface.the rest is out of limits because there are links structures which are not controllable from the c interface.felixOn 7 Oct 2009, at 00:08, dbtouch wrote:>> Hi, Felix>> You mean they are control flag used internally by K.
