Programming noob, help with gps program?

Hello! I am a noob at programming so if my questions are dumb i'm sorry! I need this goto program from direwolf20 to run after rebooting but I don't know how. I tried shell.run(goto) but it didnt do anything. I would also like to know how to make the turtle face either north south east or west. Here is the code:

local tArgs = {...}
local x = tonumber(tArgs[1])
local y = tonumber(tArgs[2])
local z = tonumber(tArgs[3])
local curx, cury, curz, dir

function getPos()
   return gps.locate(3)
end

function getDir()
   local dir, x, y, z
   x, y, z = getPos()
   --print("Old: "..x..","..y..","..z)
   while not turtle.forward() do
	  while not turtle.up() do
		    turtle.digUp()
	  end
   end
   nx, ny, nz = getPos()
   --print ("New: "..nx..","..ny..","..nz)
   if (x == nx) then
	  if (nz > z) then
		 dir = 2
	  else
		 dir = 0
	  end
   else
	  if (nx > x) then
		 dir = 3
	  else
		 dir = 1s
	  end
   end
   return dir
end


function setDir(toDir)
   while toDir ~= dir do
	  turtle.turnLeft()
	  if dir == 3 then
		 dir=0
	  else
		 dir=dir+1
	  end
   end  
end

function moveX()
   distx = x - curx
   --print(distx)
   if (x > curx) then
	  setDir(3)
   else
	  setDir(1)
   end
   distx = math.abs(distx)
   --print(distx)

   for i = 1, distx do
	  while not turtle.forward() do
		 while not turtle.up() do
		    turtle.digUp()
		 end
	  end
   end
end

function moveZ()
   distz = z - curz
   if (z < curz) then
	  setDir(0)
   else
	  setDir(2)
   end
   distz = math.abs(distz)
   --print(distz)

   for i = 1, distz do
	  while not turtle.forward() do
		 while not turtle.up() do
		    turtle.digUp()
		 end
	  end
   end
end

function moveY()
   disty = y - cury
   disty = math.abs(disty)
   if (y < cury) then
	  for i = 1, disty do
		 while not turtle.down() do
		    turtle.digDown()
		 end
	  end
   else
	  for i = 1, disty do
		 while not turtle.up() do
		    turtle.digUp()
		  end
	   end
   end

end

--=====================--
if not x or not y or not z then
   print("Must supply X Y Z")
   exit()
end

rednet.open("right")
--print (x..","..y..","..z)
dir = getDir()
curx, cury, curz = getPos()
distx = x - curx
disty = y - cury
distz = z - curz
--print ("Current: "..curx..","..cury..","..curz)
--print ("Distance: "..distx..","..disty..","..distz)

moveX()
curx, cury, curz = getPos()
moveZ()
curx, cury, curz = getPos()
moveY()
curx, cury, curz = getPos()
print ("Current: "..curx..","..cury..","..curz)
rednet.close("right")

thanks all!

On startup, a turtle (or other ComputerCraft system) will boot any code found in a file called "startup" stored on the root of its drive.

Say Dire's code was saved as "goto", you might enter into the startup file:

shell.run("goto", x, y, z)

… replacing x/y/z with the position you wish the turtle to travel to.

You could add in an extra line under that:

setDir(dir)

… where dir would be 0 for north, 1 for west, 2 for south or 3 for east. (Speaking of which, that "dir = 1s" line is a typo; ditch the "s".)

If you're still stuck, I suggest providing some more info on what your goals are.

But I just realized that when I place it down start up doesn't run until I open the gui, is there a fix for that?

Newly placed systems are in their "off" state, so they won't launch their startup scripts until something occurs to turn them "on". Generally, yeah, that'll be you right-clicking them.

It is possible to have running computers/turtles turn on new turtles; say one turtle just placed another, it can then boot that turtle in front of it with:

peripheral.call("front", "turnOn")

If a running computer/turtle is in a world chunk that unloads, it should automatically turn itself back on when that chunk reloads.

There is a known bug which sometimes prevents this behaviour though. There is no known cause or fix.

Hence "should". ;)/> But newly placed systems shouldn't turn themselves on - that much is expected behaviour!
