Hi
>So this means I fire Marathon, open the database and execute the given statement and from then on it will work always for that database? And the directory name is C:\Program Files\Firebird\Firebird_1_5\UDF\ I found this already created in the folder and I will copy the dll there. That's nice, I can also get it copied there by InnoSetup on the clients machine, wow.

Exactly. You can load entire script and run it. You can also change names for functions in that script.
Regardin Marathon, another administration tool that I like is IBExpert. The personal edition is free, if you want to try it.
