Each charater?

Is it possible to execute code in a loop for each character in a file?

What exactly do you mean?
Execute code..
In a loop..
Each character in a file?

for char in string.gmatch(file.readAll(), ".") do

Do you mean to execute different functions with their own key press? If so, then it's perfectly possible.
You can do something like this:

local event,p1 = os.pullEvent()
if event == "char" and p1 == "<key>" then
  <function>
elseif <same as above with different key>
  <function>
end

You can do something like this:

I mean to read a file and then execute code for each char in the file as opposed to each line of a file.

Sounds simple enough, but probably not too simple. I think you could have a bunch of local variables for each character, and link those characters to functions.
