Aaah. So it's (essentially) just the old print "BREAK"; technique. That's what I thought you meant, but I considered perhaps by 'binary' you meant that I could literally do some sort of 'binary search' for the line in question. Hah! I'm such a dope some times. Thanks for clearing that up. :)

    Effectively that is a binary search, as you are excluding half of the unknowns at each pass. Even on very large source files, it zeros in on the errant line(s) pretty quickly. You can do the same thing with deliberate error too.

    Enlil reminded me that the quickest way to "comment out" half of the code is to use a __DATA__ statement. Shove it in the middle to start then move it a quarter forward or back as appropriate.
