put this in top of code:
if the program name was testing.
and you called it like this: tesing print run
then tArgs[1] would be print
tArgs[2] would be run
tArgs = {...}
if the program name was testing.
and you called it like this: tesing print run
then tArgs[1] would be print
tArgs[2] would be run

Okey, lets make some code to make this easyer :P/>/>
this program is called sleepfor. It is called with sleepfor "time to sleep"
If we called program like this
the program would sleep 5 seconds.
this program is called sleepfor. It is called with sleepfor "time to sleep"
tArgs = {...} --stores the arguments you used when you called program. to the table tArgs
sleep(tArgs[1]) we sleep, with the valvue off tArgs[1]
If we called program like this
sleepfor 5
the program would sleep 5 seconds.

put "tArgs = {…}" at the top and then the data that you put after the program name can be accessed through "tArgs[1]". Or you can assign a variable to store the data with "veriableName = tonumber(tArgs[1])". Hope this helps!

I was testing this out so I typed :
tArgs = {...}
chicken = tonumber(tArgs[1])
blah = "is"
if chicken == blah then
print("Is what?")
end

It tries to turn whatever you give it into a number. If it can't, it'll return nil

tArgs = {...}
chicken = tonumber(tArgs[1])
for i = 1, chicken do
while not turtle.forward() do
turtle.dig()
end
end
EDIT: Sorry I was being stupid and did this on a computer.
EDIT2: Tried it on a turtle didn't work. Please help.

tArg = tonumber(...)
print("Going to try to move ", tArg, " times.")
for i = 1, chicken do
while true do
if turtle.forward() then
print("Moved ", i, " time(s)")
break
else
turtle.dig()
end
sleep(0.2)
end
end
I think you can just use the … straight if it is one param. Also, I think you were probably getting false when you tried to use your while loop, but I don't know why. This should help to debug, though.

What version of CC are you in? Might be a fuel problem if you are 1.4+.
If so. Fuel turtle. (google) or disable turtle fual in Config.
