Every time I liked to compare two files on a DOS machine I found that there's no program around to suit my needs. So I had to write my own...
You may compare two files of any size and of any format. If they're DOS text files (with end-of-lines by CR-LF) you may like to switch to ascii mode to get a more readable display. The only limitation I found annoying is that you can't use long filenames because I compiled it as simple 16 bit DOS program. SFC is called with two file names, otherwise it will display a short help line. If there aren't any differences no display occurs and SFC returns to the caller.
There's no need to explain much, please take a look at the snapshot. The only command that needs a word is "jump to another byte." You enter a value and SFC looks for a byte with any other value. So you can jump over huge amounts of zeroes for example.
