This program simplifies the debugging of MMIX-programs. It acts like a conventional debugger by reading a tracefile (which can be easily generated using "mmix - v") and using this information for a nice Windows-interface. But in can do even more: While conventional debuggers have the limitation to go only forward through the code, MMIX-trace can move forwards and backwards (because it only reads the trace-file). It supports the following functions:

• Single step forward / backward
• Forward to next POP, backward to last PUSHJ
• Forward / backward to any line in the code
• Forward / backward to the next / last occurrence of a command
• Display of the effect of a command, oops und mems
• Free configuration of the font size
• Workaround for a bug in MMIX that sometimes produces wrong line numbers

Installation is not necessary, the program can be executed immediately after download. It won't create any file in the Windows-directory and it won't create any entry in the registry. It only creates an INI-file in the same directory as mmix_trace.exe.

MMIX-Trace is a windows program (compatible with Windows 95, 98, ME, NT, 2000, XP). A Linux version does not exist. But it work's without problems using a recent version of WINE (I've tested that with the Knoppix distribution).
