Re: [pbmserv-dev] my moultezim program is buggy. help!

You know, you might have something there.  I am not useing IntList
but I just thought of something, why don't I just change the name
of the array so it is not called int board[] and then the compiler
will not confuse the two!  D'OH!  I'll just call the copies something
like int boardy[25]  in the recursive routines.  Thanks John Williams,
I'll try that and see if it works.
