Command: command_line
  
Syntax: 
  s = command_line() 
  
Description: 
  Return a sequence of strings, where each string is a word from 
  the command line that started your program. The first word will
  be the path to either the Euphoria executable, ex.exe or to
  your bound .exe file. The next word is either the name of your 
  Euphoria .ex file, or the path to your bound .exe file. After 
  that will come any extra words typed by the user. You can use 
  these words in your program. 
  
Comments: 
  Euphoria (ex.exe) does not use any command line options. You
  are free to use any options for your own program.
  
  If you bind your program you will find that all command line
  arguments remain the same, except for the first two, even
  though your user no longer types "ex" (see examples below).
  
Example 1: 
   -- The user types:  ex myprog myfile.dat 12345
       
       cmd = command_line()
       
       -- cmd will be:  {"C:\EUPHORIA\BIN\EX.EXE", 
       "myprog",
       "myfile.dat",
       "12345"}

Example 2: 
   -- Your program is bound with the name "myprog.exe"
       -- and is stored in the directory c:\myfiles
       -- The user types:  myprog myfile.dat 12345
       
       cmd = command_line()
       
       -- cmd will be:  {"C:\MYFILES\MYPROG.EXE",
       "C:\MYFILES\MYPROG.EXE", -- spacer
       "myfile.dat",
       "12345"}
      
      -- Note that all arguments remain the same as Example 1 
      -- except for the first two. The second argument is always
      -- the same as the first and is inserted to keep the numbering
      -- of the subsequent arguments the same, whether your program
      -- is bound as a .exe or not.
