Fb 1.5.x, throughout the entire release cycle, up to and including
4.8.7, without seeing any problems. Delphi, though. But nothing
newer than Delphi 7.

your setting for OldParameterOrdering in firebird.conf? It should
**not** be set on for Fb 1.5 and latter IBO versions...

I added IB_components.pas to my BCB project thinking I could step into
the code to see why ParamByName wasn't returning anything and it
started to work (i.e. ParamByname returned a column). I removed the
pas file and it continued to work. I guess there may have been an old
OBJ file kicking around some place, but I performed a build-all many
times.

It's a problem we put down to where 'talking to the compiler' made it
work.

Thanks for your help.
