Markus,

I'm using your genrepox a long time. Than you for this product.
I will not use mostly *: commands or inheritance, I use it for my report translation driver like your sample intl driver.

I need similar driver to modify scx files in run time: genformx !
I think this will provide an uniform way to write drivers for modifying
screen files. Why to to write such program ?

Is scx file modifying + do form faster than
do form + addobject in init ?

My problem is about writing some runtime modify form editor to
allow form modification.
I'm searching for any tool to assist in scx modification.
