Try the following
Add A Formlib component
Tools -> Component -> Add Dll
Add a Formlib object called, for example, Flib
Tools -> Add Object
In your code, assuming your form is called Form1
Flib.New1 ("Form1",B4PObject(1))
Flib.FullScreen(False)
Make sure you have a button to close the App. The False parameter should let the title bar remain (to remove that as well specify True for the second parameter). However on some devices, though not my Axim X30, it seems to remove the title bar as well as the menu regardless of the setting of the second parameter.
