w/IBODatabase, IBQuery and FB 1.0.0.794

When I execute the complete script below in IB_SQL
(as a new db with the required GENERATOR), it returns
without error.

When I run it through IBOQuery flattened out as a single
string, it returns "Token Unknown" on the first COMMIT.

(The rationale for this is that the 'DBNOTES1' in the script
below gets replaced in the string so that I can create
additional tables.)

If I remove that first COMMIT, it returns "Token Unknown"
on SET in the SET TERM in preparation for the trigger.

The script (sections):

CREATE TABLE DbNotes1(
NoteID INTEGER NOT NULL PRIMARY KEY,
Subject VARCHAR(36) NOT NULL UNIQUE,
Notes BLOB,
CreateDateStmp DATE,
CreateTimeStmp TIME,
EditDateStmp DATE,
EditTimeStmp TIME
);
COMMIT;

/* The generator referred to below is already
created in the db */

SET TERM !! ;
CREATE TRIGGER BI_DBNOTES1 FOR DBNOTES1
ACTIVE BEFORE INSERT
AS
BEGIN
IF (NEW.NOTEID IS NULL) THEN
NEW.NOTEID = GEN_ID(NOTEID_GEN, 1);
END!!
SET TERM ; !!
COMMIT;

CREATE INDEX DbNotes1SubIdx ON DbNotes1(Subject);
COMMIT;

If I eliminate the first COMMIT after the CREATE TABLE
and ExecSQL (runs OK), Close and Clear that IBOQuery, and
then run IBOQuery.SQL for the SET TERM trigger script (above),
it returns "Token Unknown" for TERM.

I presume that there are some clues to running DSQL
through an IBQuery (or other similar components)
that I need to become aware of.
