Re: Comparing 2 printouts (before and after) ?

Here is the massively parallel optical computing technique first taught to 
me by Bob A. in Pittsburgh circa 1983:

    1. Print both listings on greenbar at 10 char/inch.

       For those of you newer to the profession, that's 14-7/8" X 11" paper 
       with funny holes along the side.  The cheap stuff is kinda translucent.

    2. Place one printout on top of the other.

    3. If your Dilbertanian cubicle is lit like ours were by fluorescents in
a box 
       atop the book shelf flipper that worked by reflecting light off of a low 
       ceiling, climb up on your chair (careful! - it rolls) and use the light 
       fixture as a light box to illuminate your carefully superimposed
printouts 
       from below.  If your's isn't, hold them up against a window (only
works in 
       daylight . . . if it's dark out, go home and get a life).

    4. Mismatched characters will visually stand right out.

Hey, don't thank me.  Thank Bob!

Oh, and as I used to tell my kids when they were growing up ...

Ask me if I'm kidding and if I am, I'll always give you an honest "Yes, I'm
kidding."

I'm NOT kidding.
