Any process started with Process() or any of the List() type commands.

PickFile() is an lList() process, the only (major) difference is that the 
display has been set to display pickfile records.  Here's the rough 
equivalent 
code:
	CreateTempBuffer()
	BuildPickBuffer()
            DisplayMode(_DISPLAY_PICKFILE_)
	pick_ret = lList("Test PickList", Query(ScreenCols), 
Query(ScreenRows),_ENABLE_SEARCH_)
            DisplayMode(_DISPLAY_TEXT_)

Whatever you pass to EndProcess() is returned by the Process() command.  IE:
Keydef fookeys
	EndProcess(-1)
end
proc main()
	integer foo = 0
	// do whatever here
	Enable(fookeys)
	foo = Process()
	warn("The following is the result from the endprocess: ", foo)
	// do whatever
end		
		
foo will be set equal to -1after the process.

I don't understand what you are trying to do here...  Can you give me an 
example?

We talk about Process() and keydefs in the documentation (page 70 of the 
macro 
guide), and provide macro source for examples of the doing other things with 
Process() and List().
