The file has 41 lines with Exxxxx strings in it. My goal is to open this file while taking the first 40 lines ( as you showed me earlier) which then I will insert the eject 0,0,0 string at the very beginning one time. The regular expression as above is commented out and has worked for me in the past but it places an eject in from of every E string. Here is a picture of what I need. eject 0,0,0 Exxxxx Exxxxx Exxxxx Exxxxx Exxxxx .....( Exxx x40) and currently it looks like this which is NOT what I want eject 0,0,0 Exxxx eject 0,0,0 Exxxxx eject 0,0,0 Exxxx (x40) thanks, derek

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
