>>'oApp' is widely used acronym for Application object (some people call it goApp). The idea is to add it in the Main.prg- first app module:

>Fabulous stuff, Ed - Thanks. I've been feeling that some of my variables which I've had floating around weren't quite right. I'll chuck them in oApp. I've also got it setting up my help file references and _screen settings.

>Three further questions.
>1. I have a procedure file, is it better to put the functions held in it into oApp methods and call them specifically or to leave them in the procedure?

Up to you. You can keep both.

>2. I have all my classes in the one class library. Is it better to have oApp in a separate library?

As you see from code, clApp is created programmatically, i.e. it's not part of library. If you will include some extensive procedures then you can decide to use Custom class library.

>3. Should the library(s) be excluded from the .exe or built in. There are likely to be upgrades.

My preference is to include VCXs in Exe.
