IB6 ApiGuide.pdf will tell you what you want to know about the structure of
the error status vector. The c header file ibase.h in Firebird's \include
directory has the interface declarations and iberror.h has the C symbols
and codes.
Well, I took a look there...but maybe my newbie status didn't let me to get the information accuratelLy.
I'll take a deeper look then.

As the **InterBase !!** conversions for iberror.h and ibase.h,
respectively, the source units IBErrorCodes.pas and IBHeader.pas should be
a starting point. You'd be wise to compare the symbols in
IBErrorCodes.pas with iberror.h in your Firebird \include directory. If
you want a full list of codes and symbols, together with text messages, for
Firebird 1.5, you can download one from the Contributed Code section at
www.ibobjects.com.
The IBX sources themselves should reveal more about how IBX surfaces the
error status vector as Delphi exceptions. All else, as they say, is
Delphi. You might try posting some suitably covert questions on Borland's
interbasespress newsgroup...
thanks for the last 2 tips
