New to Lua, confused by error <eof>

I recently started taking an interest in Lua programming with a Minecraft addon called Computercraft, which involves console-based GUIs to control computers and other things with Lua. However, I seem to be randomly getting an error where the code requires something called an "eof". I have searched multiple manuals and how-tos, and none mention this particular error. In fact, I am having trouble finding anything with an error list. I am fairly new to programming, but have had basic Python experience. Could anyone explain what "eof" is?

Using ESPlorer there is a difference between "uploading" a script and "sending" a script. Use "Upload".

This is not the same issue as the one reported, but as searching landed me here...

An eof is do or then.

Usually eof means you have too many (or not enough) end statements. Paste code maybe?

Suppose I create a file with one too many end statements:

> edit test.lua

for i = 1, 10 do
  print(i)
end
end

When I run it, and lua encounters that extra end statement on the last line where there is no code block still open, you'll get an error like:

> test.lua

bios: 337: [string "test.lua"]: 4: '<eof>' expected

(from a quick test in CCDesk pr7.1.1)

Problems with the basic structure of the blocks of lua code show up with bios on the left rather than your file name; the part of bios that loads lua files will usually tell you where it was at in the file when couldn't make sense of the code anymore (like line 4: here). Sometimes it might be a bit of a puzzle to work your way from the scene of the accident back to where things got off track. =)
