MDIFF file compare this is a file compare routine based on a bit parity comparison of 2-byte sequences. Hashing was built on sequenced use of this C/C++ code where b8e is an 8-bit even bit mask and b8o is an 8-bit odd bit mask, examined via byte sequence group(s) count (file 1 vs file 2) compare. Command line requires file 1 name and file 2 name resulting in fast comparison result message. The detail switch displays all difference (lines). Useful for file compare and change tracking in document and source code files.
