Okay, well I'm guessing that what you are trying to do is remove any comments from some code, where comments are enclosed with \- and -/.

If that's the case, something like this should do it:

for (@data) {
    chomp;
    $_ =~ s|
        \\-         # Start of a commented section
        [^(-/)]+    # Anything that isn't the end of a comment
        -/          # End of commented section
        ||gx;
}

However, I suspect that you'll still have problems. In your original code you were setting the input record separator ($/) to "BOR". In your current code, this really has no effect as you're no longer reading from a filehandle. And so the "/nBOR" that you're inserting into each @data element is no longer having the effect you think it is. I guess you need to do all your processing as you iterate through the SQL result set.

But even then, you're building a list where each element is basically another list, and then later splitting the inner list out. I think you really should think about building a LoL in the first place (or perhaps a LoH). You could then get rid of that $aa = $rec[0]; $bb = $rec[1]; nonsense ;)
