ikegami's advice is correct. jtgault, Just do away with the quotes.

Other monks have also advised correctly. The error is precisely because jtgault has declared INPUT via the open command but not used INPUT anywhere further in your program. Do something with that INPUT and that warning will go away.

And, finally, my advise is also correct (albeit a bit tangential) -- if, jtgault, you use single quotes, you will not be able to open your file, however, if you use double quotes, or as ikegami is suggesting, then you will be successful.

Update: added "jtgault" so it doesn't seem like I am correcting/advising ikegami when actually I advising jtgault. ;-)
