Hi Peter

Thanks for your response.

>I would definitely include the used version of Codebook (or its download).

Ok

>Can they still compile to the EXE without the i-layer?

Nope. UPDATE: that is my i-Layer is required to compile or atleast execute the application if recompiled. CodeBook has it's own i-Layer but it is empty and the one I have is an enhanced version of the same.

>Suppose there's an error in the i-layer, can't they fix it?

My personal work, which helps me develop better (relatively :)) multiple applications. I wouldn't want to pass on the advantages, I.P. if I am allowed the liberty to call my custom framework works. Because, keep the c and i-Layers and replace the a-Layer and the data dictionary and you can build a product as good as any that I make.
