Thanks, I've got it working perfectly now. How should I print the
array to the screen?
BTW, here's the source so far:
/*Program outline
Make 5 rooms, randomly placed
Try to select all squares that touch the first square (and select ones
near them etc.)
If all not all squares are selected make 2 more rooms
retry selecting (only ones that don't have selected squares all around
them)
repeat room creation, selection trying etc.
If at any time it's close to having all squares selected delete all
unselected squares
Convert selected squares to floor (1)
