Your have a second bug. You can't match chr(0x0A) in the binary data. I fixed this by adding the "s" modifier.

This works beautifully. I tried this without the ^N for a while, but couldn't get the backreferences to work. Thanks for the new knowledge about the 'postponed eval' and the ^N. I had seen the postponed eval previously, but had stayed away from trying it due to the comments about 'highly experimental'. Thanks for everyone's help! johnbo	[reply]

$1 could be used for the first $^N, and $2 the second, but $^N is more meaningful. They're not that experimental, and they're require to do what you want to do in a match op.	[reply]
