Jeff Cuscutis [1] sent in a version written in C♯ (C-sharp, in case you don't have a font with the sharp symbol). He assured me the code works, but I can't test it as I don't use Microsoft Windows; nor have I installed Mono [2], as I don't really have a need to interoperate with the Microsoft Windows environment (at home, or at The Corporation).

About the only question I have about this version is that it appears to open the input file in text mode, and the hex dump program should work on any type of file, text or binary.
