I'm not an expert in Mathematica and would appreciate comments on why
init1 returns a list with all zeros replaced by -1, but init does not.
Its probably very simple but its confused me.

Don

init[n_Integer]:=Module[
                    {s=Table[Random[Integer],{n n}]},
                    s/.{0->-1};
                    Partition[s,n]
                    ]

init1[n_Integer]:=Module[
                    {s=Table[Random[Integer],{n n}]},
                    s/.{0->-1}
                    ]
