     // We always dig out two spaces at a time: we look two spaces ahead
     // in the direction we're trying to dig out, and if that space has
     // not already been dug out, we dig out that space as well as the
     // intermediate space.  This makes sure that there's always a wall
     // separating adjacent corridors.

     drawblock(y,x);  // change graphical display to reflect space dug out
     nextframe(40); // show next animation frame after 40ms delay

     // But the following won't work (but will compile)

     // sample code that tries to digout one space to the left:
     if (x-1>=0) digout(y,x-1);
     // sample code that tries to digout TWO space to the right IF it's not
     // already dug out:
     if (x+2<mwidth && M[y][x+2]==0) // always check for maze boundaries
