Glenn,
I don't understand what you think is the problem still.
This code should work in your example (it works with VFP6)

If !Seek(3,"test",juststem(cIDXIndexFileName))
	Messagebox('Not found')
Else
	MessageBox('Found')
Endif

The only thing I changed what to add juststem() to the 3rd argument of seek() and I changed the MESSAGE() to a MESSAGEBOX() in the ELSE statement. Maybe the MESSAGE() vs MESSAGEBOX() was the problem because it threw me off for a loop :)
