Dont Know Why This is Wrong

-----------------------------------

Hi, I am Attempting to make a Thick Line move from left to right to the midddle of the screen. I entered This code and it does not show the arm at all, can somebody offer any suggestions as to why it is doing this? 

var arm : int


process movingarm
arm:=160
for counte:160..400
arm:=arm+1
Draw.ThickLine (1, 200,arm, 200, 30, 49)
delay (50)
Draw.ThickLine (1, 200,arm, 200, 30, 0)
end for
end movingarm

Mod Edit: Fixed the syntax tags[syntax="turing"]Your code actually goes in here[/syntax]

never use process, at least not in turing, For anything other then music.
for that process to work you need to call it by using 

fork movingarm

Don't use processes in Turing. Only use it for background music. Processes are extremely buggy and unreliable in Turing. Why not just put it in a procedure instead?

e.g.
var arm : int

proc movingArm
arm:=160
for counte:160..400
arm:=arm+1
Draw.ThickLine (1, 200,arm, 200, 30, 49)
delay (50)
Draw.ThickLine (1, 200,arm, 200, 30, 0)
end for 
end movingArm

movingArm
