These two programs read in the cube data from the file vkocwordsearch_214.txt, then step through the cube, generating and printing 20 char strings for each point.

Two programs are included.  GenAllDirections.exe steps using every possible step vector (except (0,0,0)).  That takes a while, and the resulting file is pretty huge.

GenUnitStepDirections.exe steps only using unit vectors (where a step size of 19 means -1).  It's much quicker, and the resulting file is only about 9MB.

These programs take no arguments.  They both expect to find vkocwordsearch_214.txt in their current directory, and create a file named unsortedlines.txt.  If you plan to run both, rename the output file before you run the second one or your work will be lost.

I only provide these because the output files are so big! As always, on your own head be it.  I make no promises, and express no warranties!
