The following recent thread on the MIDRANGE-L list over at MIDRANGE dot COM caught my attention: Sudoku on an iSeries

A webified version of the sudoku solver is available, but I found the original version written by Dave Kahn to be more interesting.

First, Dave's Sudoku Solver is written in RPG. If you examine the source code, you'll find a writing style that exemplifies effective use of /free format and subprocedures.

Second, it runs on the green screen (or "natively," as some call it here).

A 830KB save file with everything pre-compiled can be downloaded from http://think400.dk/downloads.htm (the actual save file is here).

I fed the program an "evil"-rated puzzle, and it was solved in 32 steps.
