	Thanks much!  I *did* learn that with just FS, no need "END".
	Maybe you can help me figure out what I'm trying to do because
	I'm wedged!!

	I've got 80 or so html/php files. Most do have 

	<BODY BGCOLOR=#FFFFFF"> 

	but a whole slew do not/are missing the BG color code.
	So is there some scripto-magic way of finding out which fles are 
	missing the above string?  I know how, using an ed/ex script to
	insert this string.  

	My hacker brain seems to be on strike!
