I'm looking for a binary editor (platform doesn't really matter) that can take blocks of bytes (or bits), shift them right (extended shift, carrying bits throughout the entire block, not just shifting things on a byte or word basis), XOR, AND, OR with a repeated value (i.e. 12 means 12 12 12 ...), modulo add or subtract, etc. Anyone know of such a thing? Most binary editors I've seen are very weak in the area of binary data manipulation. --Chuck
