Perhaps I am being a little silly, but have you looked at the various
sample and tutorial applications that come with IBO? I only ask
because they are a useful way of discovering where to start.

So there were some typos in the code. This is not a "learn how to
write Pascal" forum, it is anticipated that most people will have some
idea of how to write and debug their own code.

However for a starter you could try...

for ii := 0 to ComponentCount - 1 do
begin
if Components[ii] is TIB_BDataset then
TIB_BDataset(Components[ii]).Open
else if Components[ii] is TIB_Cursor then
TIB_Cursor(Components[ii]).First;
end;

(Since the "as <type>" is redundant when already tested with "is
<type>").

If you need more info on how to write Pascal, perhaps there are some
users here that can offer some suggestions for books and lists that
can help you.
