Actually it's a subscript expression, which evaluates to either $Envfile
or the null string depending on whether $- (the current flags) has an "i"
(for interactive) in it or not.  Admittedly it looks like gobbledygook.
But it also shows how cute you can get in Korn shell.

If I hadn't seen the expression my .profile would say

	case $- in
		*i*) export ENV=$Envfile ;;
		*) export ENV="" ;;
	esac

In fact it probably should anyway. :-)
