If you are at (x0, y0, z0), the surrounding boxes are those whose coordinates (x, y, z) are in this range: (x0 - 1) >= x >= (x0 + 1), (y0 - 1) >= y >= (y0 + 1) and (z0 - 1) >= z >= (z0 + 1).

Wouldn't it be easier (as in speed wise) to just have a tiny bit of m/c and just poke the x,y,attrvalue into it before USR'ing it? A little library of such routines for BASIC to use would be quite handy I expect. :)
