I would like to ask, if there is in WorkSpace 2.5 already implemented
support for Sybase IQ 15.
What I can see is 15.x native driver bundled, but it behaves really
strange when using IQ 15.1 or 15.2, just like othertimes, when wrong
driver/older is used.

Some SQL commnads return correct results, but for example there is no
expand {+} function to see database objects.

I tried to use jconn3 bundled with IQ 15.2 on windows 32bit for my
connection, but same behavior.

IQ 15.2 ESD2 win32bit
WorkSpace 2.5, latest from 2009, according to release info, no newer
EBFs exist
