error with an if statement

Hello, I'm a noob who can't figure out why the else part of an if/there/else statement won't work. I don't know how to use paste-bin so I'll just type my simple code for trying to make a tree farming robot. p.s.the error is a bios:338 on line 10 which is where the else is and it says an = is expected.
turtle.compare()
if true then
turtle.turnLeft()
turtle.turnLeft()
turtle.forward()
turtle.forward()
turtle.forward()
turtle.forward()
reboot
else
turtle.dig()

then i tell it to keep digging up the tree.

Using pastebin is simple. Go to their website, copy/paste your code, hit submit. Done.

Second, the reason your code is not working is due to the line where you have "reboot". That is not a function, and even if it were you need parentheses to make it run.

Another thing you need is an end to the if statement.

if condition then
  --Do stuff
  --What purpose does os.reboot() have here anyway? Use a while loop.
else
  --Do other stuff
end

The main reason would be that you did not end the if statement.
And if statement goes like this:

if <condition> then
	-- Do this
else
   -- Do that
end -- need this

(applies for loops, functions, can't think of what else if there are more)

In your case, you're checking if true == true then do the code, but true is ALWAYS equal to true.
I would guess you wanted to check if turtle.compare was true:

if turtle.compare() then -- same as if turtle.compare == true then
	turtle.turnLeft()
	turtle.turnLeft()
	for i=1,4 do turtle.forward() end -- loop! :D/>/>/>
else
	turtle.dig()
end

What that loop does is it does turtle.forward, 4 times.

EDIT:
Ninja'd by what? A few seconds?!

thanks for the help and to your response remix, i did put an end to it i just didn't want to type that and i know that works because i already looked on here and fixed it possibly i may have the wrong end and again I'm just noob. again thanks for the help this just taught me like 12 things.

oh yeah by the way if you are still on this page how do you extract files from a floppy?

As in copy them from a floppy?

Use fs.copy

fs.copy("/disk/fileToCopy", "/newFileCreated")

thank you i luvs your knowledge oh and could you check out the other topic post

Also your reboot should be os.reboot()
