Thanks, I have finished the WorkLog.prg for handling all triggers!

It can divide the case when Insert Trigger is fired:
- Insert blank (without using Table buffering)
- Insert-SQL (with some non-zero value)
- Recall Record (that is unmark the delete record!)

It also take care the Append Blank than update action.
So Update Trigger handle will check through fields and log:
- AddNew Action if all OLDVAL() are empty
- Only Update Field value but not all

Thanks and take a look on it and comment! ^_~
