Here is the directory entry for that file:
-rwx------  1 rem  user  24 Aug 27  2004 h-awk.cgi
   ^ Note user execute permission needed for all CGI scripts.

** Start of listing of h.awk **
END {printf("Content-type: text/plain;charset=us-ascii\n\n");
     printf("Hello, world!\n") }
** End of listing of h.awk **

Here is the directory entry for that file:
-rw-------  1 rem  user  95 Feb 28  2007 h.awk
   ^ Note: User execute permission is *not* needed for separate program files.
(Technical reason: Because such "programs" are actually treated as data,
 read in by the awk program, not executed directly as programs themselves)
