    You can't allocate, what you don't have.

    If the array is the smallest variable size (char), you would
have to have 600*600*50 bytes for just this array and unless my
calculator is wrong, that comes out to 18,000,000 bytes!  He just
doesn't have enough RAM on his "16 Mb" system.  The scarey thing
is that he used the word array in the plural - "arrays".

        This is an OS-dependent subject.
