Procedure:

The perl scripts used in the data analysis are run from a command line.  I have used 
the MKS Toolkit (Mortice Kern Systems) to provide both the perl language, and also a
command line environment (Korn Shell).  However, perl could also be run from the 
Windows "Command Prompt" environment.  The MKS Toolkit emulates a Unix environment 
in Windows.

# DONT REPEAT THE TWO BELOW

# Read and then write report file Feb 6, 2013
# perl PlPrepareRand.txt GradientRating.txt > PreparedGradient.txt

# Generate a randomized file for each student Feb 6, 2013
# perl PlRandomizeFiles.txt PreparedGradient.txt ClassList24.txt

The above will produce .doc files, which need to go through file conversion.
Open file, accept "Windows (Default)".  Press disk icon to save file, 
Click "No" button, save in .doc format.
