The following SET commands scope to the current data session:

SET Commands
SET ANSI SET AUTOSAVE
SET BLOCKSIZE SET CARRY
SET CENTURY SET COLLATE
SET CONFIRM SET CURRENCY
SET DATABASE SET DATE
SET DECIMALS SET DELETED
SET DELIMITERS SET EXACT
SET EXCLUSIVE SET FIELDS
SET FIXED SET LOCK
SET MARK TO SET MEMOWIDTH
SET MULTILOCKS SET NEAR
SET NULL SET PATH
SET POINT SET REPROCESS
SET SAFETY SET SEPARATOR
SET SYSFORMATS SET TALK
SET UNIQUE
so if your form have private datasession you have to make this set in the load of the form. For example if you set talk off in your main program and run a form with private datasession this form have set talk on if you dont set him in the load of the form.
