>Fair enough. Why? What difference does it make?

First off, class-based forms don't have a dataenvironment object (it's null, I guess - never checked). You can add it after instantiation (I guess again, never tried that). If you have your own way to open the tables for your forms, then you just make sure that code runs from form's .load() and you're done. In a .scx, there's usually some pathing info stored in the DE, code that you don't see immediately (as the DE is a separate object, not really a part of the form, just saved with it, but you don't see it in the PEM window until you specifically rightclick on no particular control and select DE from there, but then you don't see the form).

Also, if you already have a form class, then instantiating just one form off that class is just adding two unneeded files to your project. If you can, or prefer to, manage without a DE, forget scx and live happily.
