How to draw a grid using simple co-ordinate increments.
This might sound like foolish help, but most of the people I know are unaware of the simplicity. Note: You do NOT have to make any "arrays" or how ever.
Here is the turing code, the comments in the code will explain how everything works.

% Nik Udovitskiy
% 01.15.07
% Grid.t
% Demonstrates the simple way to draw a grid using co-ordinate increments.
% Sets Screen.
setscreen ("graphics:520;550")
% Co-ordinate variables.
var a, a2, b, b2 : int := 0
% The variables used for the centre of the execution window in the "x" & "y" co-ordinates.
const centerx := maxx div 2
const centery := maxy div 2
% Procedure statement that draws the grid.
procedure DrawGrid
% Draws rectangles vertically.
a := centerx - 256
a2 := centerx - 226
b := centery - 210
b2 := centery - 180
for i : 1 .. 14
a := a + 30
a2 := a2 + 30
drawbox (a, centery - 210, a2, centery + 210, black)
end for
% Draws rectangles horizontally.
a := centerx - 224
a2 := centerx - 194
b := centery - 240
b2 := centery - 210
for i : 1 .. 14
b := b + 30
b2 := b2 + 30
drawbox (centerx - 226, b, centerx + 226, b2, black)
end for
end DrawGrid

Now, after experimenting wiht this, you'll see the simplicity.
