There are hex editing program
s, including programs with that very name, available for most operating systems and computers. Some of these programs edit

s, and some do both. I just did a quick search in Google
- HexEdit for Unix at http://www.chez.com/prigaux/hexedit.html
- HexEdit for Macintosh at http://freespace.virgin.net/nick.shanks/mac/noframes/hexedit.html
- HexEdit for Windows at
...and there are many more.
Minimalists can use DOS DEBUG, while those with (somebody else's) money to blow can buy Symantec's Norton Utilities. A high-powered programmer's editor like Visual Slick Edit will also edit files in hex, as an option.
