The install guide (http://arclanguage.org/install) is out of date. For one, the latest Arc (which works with the latest versions of mzscheme) is 3.1, which you can get from http://ycombinator.com/arc/arc3.1.tar. Secondly, mzscheme -m used to mute the "Welcome to MzScheme" banner, but now:

  $ mzscheme -h | grep "\-m"
    -m, --main : Call `main' with command-line arguments, print results
So, just try

  $ mzscheme -f as.scm
or, if you're using the latest (which was renamed Racket: http://racket-lang.org/new-name.html),

  $ racket -f as.scm
You might also notice that in the newer versions, ^C at the Arc prompt doesn't put you back into the Scheme REPL like it says in the install guide. If you want that option, use

  $ racket -i -f as.scm
But that will display an extra "Welcome to Racket" sort of message. See http://arclanguage.org/item?id=10488.

Also, a couple suggestions:

(1) In the future, your post titles should be more descriptive; using more exclamation marks doesn't get you more help. :P E.g., you could've titled this post something like "Weird error. main: not defined or required into the top-level environment".

(2) To format code, put a blank line

  and then but two or more spaces before the line of code
  (and also for subsequent lines of code).
If it doesn't work right the first time you post, you're allowed to edit for a certain amount of time. A quick formatting reference: http://arclanguage.org/formatdoc.

Good luck and welcome to the forum!
