>1. What directory is your form in when you're developing?

The program I'm developing is Gsystem

>2. What directory is your EXE installed int?

It's C:\Program files\Gsystem
>3. What is the exact command you use to call your form?

Just simple "do form mainform"
>4. What happens if you copy your form into your installation directory?

After I copy the whole program to the installation directory ,when I call other form ,like "do form b" ,it will tell me that File not found "C:\Gsystem\b.scx"

>Please post the real ones. Thanks. FWIW, I always use a main prg (instead of a form). It necessary for me, so I've never used a form as a main module, but I've read posts from people who hint that there maybe some limitations with the method. (And that's where you can SET PATH and SET DEFAULT and do some of the other Application level things, like issue READ EVENTS).

And ,what you mean is write a prg that do the function like call form ,do process and etc. ?
It seem a nice method but I haven't try b4.
Thanx for your help ^_^
