Subject Script component does not accept some commands

I am using the script component to update the database structure, this has worked in the past w/o problems. What I did was creating the script in IBExpert, adapt it some and let it execute by the IBO script component.

Now for the first time, the script needs to do a reconnect in the middle of the script, so instead of using an existing connection it needs an initial connect to begin with.

That's where I get an error, IBO complains that the connect syntax is not valid.

My question now is:
If I have a working script from IBExpert, should this work as well with a script component.
