DDL Create Trigger script fails - firebird

Question

A DDL script to create a trigger (source below) fails with 2 errors:
Statement failed, SQLSTATE = 42000
Dynamic SQL Error
-SQL error code = -104
-Unexpected end of command - line 3, column 44
After line 0 in file C:\CRMDemo\Database\DDL\Trigger_Orders.sql
Statement failed, SQLSTATE = 42000
Dynamic SQL Error
-SQL error code = -104
-Token unknown - line 1, column 1
-end
At line 14 in file C:\CRMDemo\Database\DDL\Trigger_Orders.sql
(line 3, column 44 looks like it may be the closing parthesis).
I can't find any information about errors 42000 or -104.
The trigger is designed to assign a record number from a generator, which does exist. This trigger works properly in Interbase from the same script.
The only thing I can think of is that the column size, Integer, is incorrect for the value returned. But the documentation says the value may be truncated but should work for the expected value (1).
CREATE TRIGGER ORDERS_GENERATE_KEY FOR ORDERS ACTIVE BEFORE INSERT POSITION 95 AS
begin
NEW.ORDER_NR = GEN_ID(NEW_ORDER_NUMBER, 1);
end;
Firebird is ver 2.5.2, just downloaded. Windows 7. Database should be 32bit.

Answer 1

If you run your statement using isql utility take sure that SET TERM operators are used:
SET TERM ^ ;
CREATE TRIGGER ORDERS_GENERATE_KEY FOR ORDERS
ACTIVE
BEFORE INSERT
POSITION 95
AS
begin
NEW.ORDER_NR = GEN_ID(NEW_ORDER_NUMBER, 1);
end
^
SET TERM ; ^
