Still being a relative newbie to FP I'm curious as to how long DataSessions have been around.

I'm more curious as to how they are actually created from a form,formset or toolbar.

I've got a .prg which during its execution may or may not open other tables in my db if n when records from certain tables are deleted.

By default all tables opened during the execution of this prg are opened in the default datasession.

Is there a way to get this prg to work in its own data session?

...

Sorry<s>, just answered my own question,
put the code or even just call the prg from within a form which is set to private data session.
