i'm working on it already, actually, and will edit it in here.

EDIT:
The main restriction of our last map drawing style is that it doesn't allow drawing different spots in a tile map larger that 12*8, but rather only draws a single screen. here is a simple example that uses bytes for map data (because usually people have more that 16 tiles) and allows the map to be scrolled with getkey.

[HEXCODE]->Pic1
[MapDataInBytes]->GDB1
0->A->B //A and B are the x and y coordinates in the tilemap.
<map's width in tiles, minus 12>->X
<map's height in tiles, minus 8>->Y
Repeat getkey(15) //repeat until Clear is pressed

if getkey(3) //if right key
A<X+A->A //A is increased by the value of (A<X) which can either be 1 or 0, meaning that A will be incremented unless it equals X
end

if getkey(2) //if left key
A-(A>X)->A //similar to the last line
end

if getkey(4) //if up key
B<Y+B->B
end

if getkey(1) //if down key
B-(B>Y)->B
end

For(M,0,7)
For(L,0,11)
PtOff(L*8,M*8,{B+M*X+A+L+GDB1}*8+Pic1)
end
end
/*
/This is a fun section to describe. L*8 and M*8 should be fairly obvious in the first and second arguments.
/B+M*X is, because of Axe's lack of order of operations, interpreted as (B+M)*X. This will give the Y coordinate
/in the map data to read, because in order to find Y coordinates in a single dimensional list, one has to
/multiply that value by the total width of the map. A+L then gives the X coordinate, and adding GDB1 makes it point to
/the tile map data.
