Hints for using BoxMeyer.exe for Math420 in the Washington University
  ArtSci Computing Laboratory:

(1) Find a free computer running Windows.

(2) Use a Web browser (e.g Internet Explorer or Firefox) to go to the 
  Math Department Web site (www.math.wustl.edu)

(3) Look for Course Syllabi on the Math Department Web page
  and click on Math420 (for the current year). This will take you
  to the Math420 Web site. (You can also go through my Math Department
  Web page and then click on Math420.)

(4) Click on Handouts and download BoxMeyer.exe. The only choice
  may be to download it to the Desktop, which is OK.
  (BROWSER NOTES: If you use Internet Explorer, the default `Desktop' 
   appears to be for an account (`labuser') whose Desktop is not 
   visible. However, with some effort you can find the correct
   Desktop - it is higher up in the `Save To' directory tree.
   In Firefox, RIGHT-CLICKING BoxMeyer[.exe] allows you to save
   it to c:\temp (SEE (5) below), but if you LEFT-CLICK instead, 
   the only option is the Desktop, which is perfectly OK, except 
   that you will have to do some extra work if you want to do 
   command-line operations in  c:\temp -- again, see below.)

(5) From the Windows desktop, click on
      Start | Programs | Math408-Prompt
  where | means ``and then click on''.  This will open a console window
  (like a standard Windows ``DOS-Prompt'' window) except that
     (i) the colors will be black text on a white background, as in
       Notepad, instead of the default barely-legible gray text
       on a black background, and
     (ii) the console window will open in a Windows directory
       that is easy to find from My Computer or Windows Explorer,
       specifically  c:\temp

(5a) NOTE: To see the contents of c:\temp from the console window, 
  enter  dir  (followed by Enter) at any time. You can delete files 
  by entering del filename, and even delete all files in the directory 
  by entering  del * . (This is a `temp' directory, so that other
  people shouldn't be unhappy if you clean out the directory.)

(6) From the Windows browser, download one of the example BoxMeyer.exe
  input files (PBExamp1[.txt] or FF84Ex2[.txt] --- the file extensions
  may not be shown) into  c:\temp

(7) From My Computer or Windows Explorer, DRAG AND DROP the example
  input file (PBExamp1 or FF84Ex2) on top of the Desktop Icon for
  BoxMeyer. The output file (for example) PBExamp1.txt.out[.txt] will
  appear in c:\temp

(8) Click on the output file to read it in Notepad

(9) Use Notepad to write your own input file in the same format.
  Repeat step (7).

NOTE: As an alternative to Drag-and-Drops, you can copy BoxMeyer.exe
  to c:\temp  and use command-line operations in the Math408-Prompt
  console window. To copy it from the Desktop,
    (i) Enter  My Computer | My Documents | Desktop
      (the Desktop icon will appear in the left panel)
    (ii) Highlight the icon for BoxMeyer[.exe] and either enter
      Control C  or  Edit | Copy
    (iii) Find  c:\temp  in My Computer (the same or a different
      instance of My Computer), hightlight c:\temp (that is, the
      right panel) and either enter  Control V  or  Edit | Paste

The program BoxMeyer[.exe] will now appear in  c:\temp
and should be visible if you enter  dir  at the command line
in that directory.  You can now run it on an example input file 
by entering e.g.

   BoxMeyer PBExamp1

at the command line in the console window (followed by Enter).
The output file  PBexamp1.out[.txt] will now appear in the
directory. Note that the name of the output file is slightly
different in this case: To get the same output file name as before,
enter

   BoxMeyer PBExamp1.txt

instead of BoxMeyer PBExamp1.

SECOND NOTE: If you are happy with Drag-and-Drop operations and
reading/writing files in Notepad without using command-line operations,
you can skip steps (5) and (5a) above. 

However, command-line operations give you more control over the program. 
In particular, you can use command-line options to customize how 
BoxMeyer.exe works instead of entering options on the parameter line 
in the input file. (See the Documentation file - ReadMe_Doc.txt - for
more details.) 

To get a summary of possible command-line options, enter

   BoxMeyer

(followed by Enter) from the command line, without any other arguments.
For example, to run BoxMeyer on the example input file FF84Ex2.txt with 
the command-line option p=0.45 (which sets the Bayesian parameter Pi=0.45
instead of its default value Pi=0.25), enter

   BoxMeyer FF84Ex2 -p0.45

The two command-line arguments (FF84Ex2 and -p0.45) can be entered
in any order. The prefix `-' indicates a command-line option instead
of a file name. Thus DO NOT begin an input file name with -.

More options are available from the command line than are available as 
parameter-line options, and you don't have to rewrite the input file 
to use them.
