There is almost always a problem when creating an SQL trigger and the trigger's file is in use. I found out that using a UDF to do the required computation makes this process much easier. Exclusive lock of trigger file is needed only once. Later you can test and change your UDF without any need to recreate the trigger program -- in the foll. Example lot no in FSO file is determined after an allocation is created in ECL file. This logic is entered into the trigger program, which calls the nextlot() UDF for newlot value.
