Ouch! I hadn't thought of that.

Nor am I. Unless there is a DOS edit.com guru out there...?

I was trying to do two things - (1) provide a utility, and (2) offer a
useful technique. I think the technique still stands, but with the
constraint that the input file can't contain ampersands.

I've written a little java program that can be called with jview (I hope
a reasonable assumption in most windows environments) and modified the
batch file. This should rescue the utility, if not its dignity.
